a 500cfm ro 650cfm Edelbrock Carb??? I was told to put the 500 on my new high perf. 305 but Ive never touched a carb before....

 

A 500 should be fine for a stock 305, but if you plan to mod in the future you might want to consider a 600cfm.

 

Whats the difference... between the cfm's???

 

Also I was wondering how much horsepower I will gain from it instead of my TBI

 

600 flows more air than a 500. cfm means cubic feet per minute so you see that 600 is more than 500 cubic feet per minute. I think a 600 would be optimal, I'm running a non computer controlled q jet with 592 cfm on my 305.

I don't know how much power you'll gain, that's tough to answer, anyone have experience with a tbi to carb swap?

 

I hear TBI is just as good as carb, it just got a bad wrap because of the LO3.

 

I'm using a 600cfm on my 350 and seems to suit me just fine.

 

I think you should keep the TBI and upgrade what is underneath it.

 

Yup and just an FYI, it flows 520cfm in stock form.

To figure out how much carb you need, I usually use the formula:

cid*max rpm/3456

I think it goes something like that.

 

I'll consider TBI unfairly blacklisted as soon as some people w/ TBI combos start running what their combination of parts would imply, rather than quite a few tics off what any reasonable person would expect.
I'd love to be proved wrong on this. For years i was one of pablo's only real supporters. You know what. Even he gave up on it, swapped to carb and is running a lot better. Once his car gets out to him i'm sure it will show it on paper too.

- doesn't need a flame suit cuz TBI just don't light the fire

 

What exactly should I do? Im mainly swapping engines due to the fact that mine has 206,000 miles on it. It still runs great but I know its time to swap it. But I wouldnt mind a little more power.

 

Did you get this new (305) engine for free? I hope so, because that would be a odd thing to do... The only reason anyone would replace a LO3 with another LO3 would be because they were either broke or retarded. If you have no cash, then do the swap. That's cool, we've all been there. But if you are just swapping engines to swap engines, please go with a 350. They are just as cheap and will give you a lot more potential to go fast.

FYI- TBI= Toilet Bowl Injection... Go with the carb. I wouldn't go any larger than a 600cfm on a 305, it doesn't behave well.

 

STUPID I am RETARDED Im not! Well I am broke and Im just buying something to hold me over until I can finish up on my 383..... Which will be a while. So I found a brand new longblock 305 really cheap.........$500 dollars with all performance parts. So that will hold me over for now.

 

So how many TBI engines have you worked with?

Truth is people just havent tried it. I've worked with almost every induction system available, and it isnt the TBI that makes the car slow, it's the parts that go along with it.

Ed, honestly there are quite a few quick TBI's on this board. One example is Jon's 13.8@103 in the 1/4 with a slipping tranny.

 

I still have my TBI and I am very happy with it...

 

Worked on... 3

Blown away on the street/track... 300

A carb is so cheap and easy to make faster than a TBI it isn't even close of a comparison. No chip, psi isn't a real concern, no injectors pooling fuel in the restrictive intakes, among other things...

 

I'm sorry, but a vortec headed 350 @ 102mph (according to his website) is nothing special. If i come close to that with a stock headed 305 can we move this to the TBI board and make it a a sticky

 

What should you do? LEAVE IT ALONE!

No point wasting money on a 305 when you are going to get rid of it later anyway. A 305 for 500 bucks? LOL! Its probably in worse shape than what you have now, I dont care if its rebuilt or not. And you'll never get your money back out of it. Stick with what you got, and save the 500 bones for the 383.

 

Actually Its not in bad shape. Its all new. The guy couldnt put it in his car because he totalled his z28 and was seriously hurting for cash so I go a Steal. Trust me I wouldnt buy it if I didnt have it looked at by my mechanically inclined friends.... Besides I searched for better options but this one was my best one. When I get my bonus I will have more than enough to Supe up this car and buy me a Firehawk. So Im just holding on until then. I know everyone is calling me stupid but I really didnt have the money to do all this and Ive got 206,000 miles on my current engine. So with all this new stuff and some of the old stuff, I will have much better performance........................................I hope.

 

Ed what do you have done to your 305 exactly??????

 

\

See, us TBI guys couldnt get to that without changing our heads. You must know that they have valve shrouds inside of them that restict airflow at higher engine speeds (if you dont I have pics).

I'm not here to argue about petty things like times. I like the way my car drives, kicks carbed Chevelle/Novas asses and knocks down better mpg than any carbed car I have come across.

Slowstandeater, I think you should just keep the TBI since it's there anyway. You can maybe think of a swap for another induction system later on when it's maybe necessary, but for now the TBI will support what you need to get done.

 

I'm not arguing, just pointing out that TBI is a poor choice when it comes to trying to make power as far as all the evidence i have seen suggests.
And yes i'm aware that most TBI engines came w/ swirl port heads, which makes a great excuse for why they are slow stock. But when you swap engines and run one of the best iron street heads available and ONLY go 102mph, i see a combo running way below it's potential.

 

Well, Bort is running almost 99MPH... on a 305. And he doesnt have headers.

 

bwahaahahahahahahaahahahahahahahaahahaahahahaaaahaha

 

to ed,
the thing to remeber is the weight of jon's car. he is a serious electronics junkie and carries a full stereo system w/ subs, a lap top, and all kinds of other excess weight in his car. that day at teh track his car weighed a over 3600lbs. when we calculated teh rwhp from teh weight and trap speed it worked out to 290 at teh wheels. that means at teh crank he is making 340-360 at teh crank, i woudl say that is pretty good for a crate motor that is rated at 330hp. especially when you consider that even jon will admit there is mroe tunign to be done.
it may not be performing wildly beyond the expected, but still better than it is supposed to be. i am sure we will be seeing even more performance when jon gets hoem from college for the summer and can get soem track time under his belt and more tuning.
no flame ed, just wanted to let you see it from the other side a little.

to biochem,
we can all sit here and debate tbi vs tbi vs carb all teh live long day with no oen proving any oen wrong beyond a shadow of a doubt. but there is one very important thing about digital controls that i think you are missing, infinately adjustable timing control. you can easily set up any of these induction platforms to getteh air/fuel needed to make power, but without the ecm you are stuck with what amounts to a good average of teh timing you want. with a computer you can set it up to read and react off the knock sensor or you can just use the sensor to tune the timing on your own. it also allows you to do things like setting up timing retards based on mph, say you wanna go for that big mph through tthe traps, just set up the computer to starting pulling a little bit of timing at a certain mph(read from the vehicle speed sensor) and blamo!, instant mph boost.
these loops can be set up for any condition too. for mileage you have it read for a constant vacuum on the map sensor and adjust fuel/timing for highway driving, you want you car to start easier and warm up faster you can adjust the warm up loop timing/fuel.
that is the real beauty of digital controls.

Point isn't that Jon's car might be under the weather some. But IMO thats what happenes to all TBI cars once they get into / past the low 14s. There is always something wrong, an excuse, etc. Wasn't meant to be anything personal on jon.
I really think it'd be great if somebody proved me wrong, and TBI cars actually started moving. Whatever happened to your project?

 

yeah Timeslips are for *******! (If your not here to argue about "petty" things like times then what the hell are you souting your mouth off for ?)

btw My car ran 98.6 mph In full street trim in 105* degree Weather. Open element drop base aircleaner, Too.

Including a Sub box and all that.


The Carb is from a 1979 firebird 305, which i freshened up with new gaskets and DR rods. 74 primary jets.

ive gotten a best recorded 23 mpg w/ 3.42 gears out back. that was at about 80 Mph.



That is all Completely true, and a great reason to go EFI.

If of course by EFI, you Mean TPI...

Id rather run my Carb with my "Average" Timing Curve and turn better MPH and times thatn 99.9% of the TBI poulation, and get comparable Mpg to boot. ( with 180K on the clock, none the less )




peace~

 

I STILL think two TBIs would be a good answer, as long as it isn't done ala CFI mode....

I may be getting the results from that setup on my S-truck when I get it wrapped up. There are lots of two-carb intakes just begging for adapter plates and TBIs.

If all you want to do is run and run reliably, keep the TBI. You've already stated that you're building a stroker, so don't waste your cash on a carb that would be too small for it.

 

I didnt shoot off my mouth at anytime. And I didnt say timeslips were for *******, crap etc. I just didnt want to argue about them. The post was about "what should I do with my 305?" and not "how fast can a TBI go?" so thats why I said that.

But who cares he should just put a carb on his engine. While he's at it, he could put some double hump heads on, take out the roller cam and go flat tappet, then maybe instead of that cd player get an 8 track yea that would rock. Who needs radial tires when you can have skinny bias-plys? How about replacing that digital clock with a sundial?

I drive a carbed car to shows and drive my TBI car everyday. I know why GM went from a carb to TBI on all their carbed engines. There is a reason. I would never switch my Fuel injection to carb on my Camaro ever. Even if it may be holding me back, I know that it's easier to drive and super reliable. The only reason carbs still survive today is because they're so easy to setup and that's what racers like. They dont like to spend all day getting the proper parameters. It's (almost) a bolt on thing to do that will give you (mostly) reliable fuel delivery. Ease of use is why carbs are used today, not because of their power levels.

I have an unbiased view. I work with 2 carbed cars (and race one) and work with a TBI car.

I prefer the TBI.

 

SSE:

What cam is in this engine? From the talk on the GMECM list, the guru's there can tune TBI for a cam with a duration of about 235/235 0.050" as the maximum. This is for a 350, I guess it would be even less on a 305 (but I'm not sure).

 

I took it personal and I think that considering TBI is the "non-performance EFI" I'm doing something write to be running a 13.8 @ 102. Not to mention there are probably only 3 or 4 of us TBI guys compared to the countless number of TPI and carb guys.
I'm a minority in the f-body world of performance and I don't mind it. You can say that TBI can't run if you saw my car and drove in it you'd understand why it's a 13.8 and not a low 13. The only thing "RS" about my car is the body. Suspension and everything else is all about handling. This summer I'll make my car drag setup and run it just to see what I can do with this motor.
Be ready to eat your words...only problem is that I've a full time student, part-time job (30+ hours a week), and have OTHER important things in my life so until this summer you're right, TBI cars don't seem to run.
Oh yeah, wow, I just got 23mpg on my way back from Englishtown raceway swap meet this weekend and that's with ~3550 average weight (gas dependant) and 3.73 posi with only .7 overdrive and 26" tires. BLMs were at 128 but timing is still a guess.

 

JP how are you getting your 305 to do that if you dont mind me asking? If its possible I want to do it!!! Theres not a better feeling than giving a 4th gen a run for its money in an RS!!

 

he is running a 350HO. damn good motor

 

also, if you guys want the ultimate carb/tbi showdown, i am installing the exact same crate engine into my camaro this weekend, so i will have track times some time soon. setup will have a 600 performer on it, not the best carb candidate but oh well.

 

I don't wanna get myself deep into this and don't have the car or experience to back myself up much. But I think a lot of the reason the TBI platform never saw much aftermarket development is because most people who have the $$ or intent to heavily mod their cars proabbly bought a IROC/Z28/Formula/TA instead of a base model car to begin with.

The other problem is that so much has to be done to make a TBI motor REALLY perform (like faster than 14's).

I think if aftermarket companies started supporting TBI cars more, they'd open up a very large market because if you look at production numbers, there are a LOT more low output cars than HO cars.

 

lol, the problem isn't lack of aftermarket support, all you need is a carb intake, and bigger TBI units and injectors are readily available. You can also run any computer you want, whether it be stock, a 747 from a truck, a 730 from port injected engine, or even an aftermarket ECM.

The problem is, noone can make a TBI run comparable times to a port injected or carbed car. My contention in this debate is that TBI is an inherently flawed form of fuel delivery when it comes to making power. Just like edelcrock carbs are consistently down on power to a holley on the dyno/track, TBI is always down on power compared to a gremlin sitting on the intake spitting fuel down the heads.

As for why GM switched to TBI, thats simple, it is more reliable and consitent when it comes to the average non-enthusiast, the kind of people that dont even know what is under the hood or change their own oil sure can't be trusted to clean a carb every now and then, andmaybe turna screw once every couple years if the choke goes out of adjustment, etc.

None of my carbed cars ever had a problem starting in even the coldest of weather, and they all knocked down great mileage too. My 85 Z28 had a 350 that i paid $1000 for the complete longblock with a wolverine cam in it and ran 13.91 @ 100 on a 3.08 one legger rear...and it had garbage mid 70s 305 heads on it (told you it was an el cheapo machine shop special.), knocked down 26mpg on the highway, and never had a problem starting on the FIRST turn of the key even on sub-zero winter mornings in state college PA. With gears and a posi alone i would have been way ito the 13s and probably picked up a couple MPH too by letting the engine work. With a bigger Y-pipe (it had an LG4 sized Y/cat on it) it would have picked up more than a few MPH. I won't even speculate what it would have done with heads that flowed more than 180cfm on the intake, let alone 240 as vortecs do....It never got those things because i was also a poor college student and then it got stolen.

Hey, it's a standing challenge to TBI to get it to run right. JP, you get that vortec headed 350 to turn 106 mph or so and i'll say you're getting close to making TBI seem viable. Once a few people build TBI combos that run near 110 it'll seem like at least an option worth looking at. When somebody puts a NA TBI way into the 12s, then the bashing can end. Until then, all the evidence i've seen suggests TBI just doesn't work once you get near 300hp, let alone beyond.....

 

And your point is, Ed? You turn around and make carb the best looking thing this side of heaven, when in fact you are looking at 1320 feet down the road.
I have the feeling that TBI has a lot more potential than any carb setup out there, and being that I have finally worked my way through the kinks in my system, a dyno is due any time now.
I'm sure you impress everyone with your 1/4 mile times with your carb setups. Truth of the matter is, you want to make TBI look like it's the worst form of fuel injection there is.
Unfortunately, you are wrong. There are several of us that have TBI systems that are coming to life on the boards, and as you said on the TPI board, TBI is JUNK.
I disagree with you. The only JUNK out there are the people talking JUNK about systems they don't even start to understand. They give up. When you consider the economy platform that TBI was designed for, and the gains that have been made, I think you should stop this petty talk about TBI.
If all your life circles around 1320 feet, all the more power to you. I built my system for going over mountain passes, and passing up carbureted vehicles that lose air as they are climbing over the pass.
There are disadvantages to carb systems. I feel TBI has a hell of a lot more potential, and you are bashing something that needs not to be.
The base engine design of TBI was built around fuel economy, and now you can take high performance engines and use manifolds that are primarily designed for carb application, and build a decent streetable car.
Now that people are doing it, YOU are making excuses and making yourself look like a fool. Stop this bashing on a system that has MORE potential than you think.
My .02

 

Lol, my life doesn't revolve around 1320, but it does make a handy metering stick for power output. You see, if you're not talking about some form of measured performance, then you might as well be driving a honda. Those guys think their cars are high tech and fast too, but strangley the only place they ever show up is my rear-view mirror?
How many times do i have to say that i welcome the prospect of somebody making good power with a TBI combo. But so far, all of the TBI combos that have been put to the test fall short of where they 'should be'. I understand that some cars might have issues or a legitimate excuse, but when ALL of them fall short, you have to assume their is a basic flaw.
The other side of the coin is you guys that don't even have performance numbers. Don't you think that maybe YOU should be careful running your mouth when for all you know my stock 305 might leave you in the dust. If you don't know what your car runs or turns on a dyno, you are just talking trash. Just because it feels fast to you, doesn't make it fast and doesn't give you a leg to stand on in this discussion. If you put down some good numbers, you can feel free to resurect this thread and shove it in my face. And you know what i'll say. It's about time somebody got a TBI car to run good, congratulations. But until somebody has proof of a stout TBI combo, why do you keep wasting our time debating how great your car feels? Thats ***** talk right there.
I never said making good power with TBI is impossible. Just that it seems as much since noone is doing it. Thus, i can't in good conscience recommend it to anyone trying to go 'fast' since i know what an uphill battle they will face. It was TBI guys that opened pandora's box in this thread by saying that TBI was better than a carb, and he should keep TBI. If the poster wanted slow TBI guys gving him advice he would have posted to that board. Apparently he realized that noone was going fast over their and decided to test the waters elsewhere.

 

This is funny and all...

The reason TBI came about has nothing to do with being 'better' or 'worse' or 'more fuel efficient' or whatever I keep seeing applied to it. The ONLY reason GM ever went to TBI is they were forced to by the EPA. In typical government fashion, they made a decision based on rumors and theory, and ran with it. Everything else you want to state about why is your opinion and your opinion only since that is not the real reason GM went that way.

For all you TBI guys getting your panties in a bunch, sorry but this isnt a bash its a representation of facts. Anything bad you infer from this reply is your own doing, not mine.

 

That would be your opinion. I think all of the above is the reason TBI was introduced. Saying it was only the EPA is a joke. The cost of a TBI system is way less complicated and more reliable than the ccc setups so don't even start.
I think you do nothing but bash TBI, you are on a nasty powertrip. It makes me sick to think that you're a moderator when in reality you're "opinion" always seems to be a threat. Let's just recall the "I stated before on the TBI board about making claims of grandeur like they were fact. Dont even attempt it here because I will lock and/or transfer this post." Who are you to say people can't use the internet to imagine or design something new and different? **** it....acording to all the posts I ready from you, we should all stop wasting our time and jump on the big band wagon out of town, slap down some money and buy a new car....
You are no friend of mine considering you seem to have a very strong opinion against TBI yet you have never actually tooled around with them enough to have a half-whits experience! You tell me that I've never had a really well tuned carb on my car or MPFI so I shouldn't talk about how great TBI is yet you have absolutely NO idea what TBI would do on any of your own vehicles! In my eyes you're a hypocrit to the nth degree. You're like the complete anti-christ of TBI...I can see you now quoting magazine adds for edelbrock or compcams!
You, Drew, Kevin, Ed, and the rest of the "no experience with TBI because you've never heard of it running well" can go drop off the face of this earth. Tim, Brian, Joe, Bruce (Grumpy), Joby, Pablo, Fastbroker, and the rest of us non-conformers will tell you that YOU are the one wasting money. It's all about interest and I can definatly see the advantages of carbs vs MPFI vs TBI. Wetflow, dryflow, it's all bull and you guys just didn't have the character to do something out of the norm so go have fun following all those other guys, I'd rather have something different.
I have zero respect for people that talk trash about another persons car when they themselves have no clue what it's all about. Go blow my exhaust pipes and if you want ME to eat my words, show me a car exactly like mine with a carb and TPI and tell me my car is slow! Until them, stop comparing somebody ELSEs car to somebody you don't even know and then telling them they'll get their threads deleted because it isn't "fact."
Sometimes I just think you are scared that TBI will be just as fast and prove that you've wasted not only your money but your time with all those complicated and expensive MPFI systems.
If you want me to run a 110mph then maybe you should show me a car that has my motor with a carb and is doing that "110mph" trap speed!!! Until then, shut your pie hole.

 

Sorry I get a little bit heated when these arguements come about.

Points taken, sorry.

But

There are a few issues I need to straighten out:

Madmax:
The reason that GM went to TBI was because of EPA/CAFE ****'s is not something you can attest to because you are a secondary source; as all of us are. None of us could be viable for the reason why GM went to TBI because we weren't on GM's board of engineers. We are all secondary and the source can be manipulated in different ways.
Did the EPA force GM to go to roller camshafts? Maybe, but more than likely it's just GM making everyone's life easier and moving on with techology.

Ed Maher:
The real problem here is ignorance. I dont go on the carb or TPI board, you dont go TBI board (hey! you're the moderator for the TPI and carb boards!), so how can we both be experts on tech and times for the different groups? truth is, we can't.

Snowdog:
Most people live 1320 at a time. The times are a good indicator of power levels but do I have time to go to the track in between sports, full-time school and work? Not often. How many other people can say that too? Probably lots of TBI, TPI and carb guys. It's just the way it is. Ask JP when he went to the track last and why he hasnt.

And now that JP's thrown in his view on the entire subject, this post is now done.

 

Look fellas, i don't claim to be a TBI ***. And you're right, i have no intentions on wasting any time or money on a TBI car. If i bought a TBI car as a driver i would take the TBI off and throw on an adjustable regulator and run a carb. I would retain the stock computer and dizzy just cuz i have the burning equipment to set the spark curve and tell it to ignore the lack of TBI. But thats off the subject...

JP, i don't even know what to say to you. Apparently you're losing your mind over the whole issue. Doesn't it suck when you show up to a gunfight with a knife? All i want is some timeslips from somebody that has run a respectable ET for the given combo. Instead all we get are a bunch of excuses and / or opinions. How am i giving an opinion by saying that i want to see numbers or you're just fuill of it?

As for locking or moving TBI related threads on the TPI board....thats my prerogative for the content of the board i moderate. If you want to talk about TBI, go to the TBI board.

I do think it's funny that you mentioned Pablo when he swapped to a carb and loved it. You act like i don't know anything about TBI, or the kind of work you guys put into it, if you're still in the poor college student phase of things i'd say i have a few years in the game on you, so i'm not even worried about qualifying myself to you.

And iroc, i don't need to be a TBI expert to see that noone can show me a timeslip for a strong running TBI combo. If you want to make the same request on one of my boards, be my guest.

And for my final words. How many times in this post did i say i wanted to see someone make one run. I'm just curious.

 

Obviously your 'heated' mind has clouded your ability to think. My statement is not 'secondary', its fact. Call the EPA if you want. Its law. Its in the books. Carburetors were banned as an induction system and could no longer be used on production vehicles effective Jan 1, 1988. GM, one way or another, was forced to get rid of carburetors and the TBI was a viable choice since they had used similar types of setups and it was inexpensive to produce.

Look, if youre pissed off at me I dont care. Why dont you find a nice high building to jump off of if you have such a problem?

I'm not going to even bother replying to any of your post, its a waste of time and effort.

 

Obviously you haven't spent any time looking for strong runing TBI or you would have read about Grumpy's 454tb on an extreamly mild 350 that was running 99mph and 13.9's all day. Do a search for it and you DO need to prove to me that you have even the slightest clue how to tune wet flow EFI. If you also think Pablo went to a carb because it's better than you a ****ing idiot. I talk to Pablo all the time and I hope he replies to this to tell you that he's not staying carb and that he's going back to tbi asap. So there are your "facts" now shove it and get off all the tbi guy's cases. Oh yeah, and how about some time slips of YOUR current ride.
I must say that I appreciate you guys giving me more incentive to strive for more mph and lower ETs. I don't appreciate all the smack talk. A little can be considered constructive critisism but you guys went way overboard. I'm ashamed to even be called a moderator after you guys beat on ever TBI acomplishment as if we're mustangs or worse...imports!

mad, **** off or go to hell, either way is fine by me. Who cares if you don't reply to any of my posts ever again? I can't think of any time you've actually helped me, all my help comes from the people that don't talk to guys that have tbi like their on a lower level of the thirdgen scene.

 

You first.

I've asked Dirk and/or Brad to pull your account. I havent personally attacked you (your car maybe, but not you) and you are seeing fit to do so to me.

BTW, you may 'talk' to Pablo alot, but I've been down at his place a couple times in the past month or so. I already know what he's up to besides getting shipped off to Okinawa. I also know he said you were really pissed off at me, which:

1. I dont understand why. Like I said in the email, I wasnt even trying or wanting to **** you off, and yet you took it that way. If thats a problem, well then YOU are the one with the problem. Hell, I think thats kinda obvious now.

2. I could care less how you feel about me after you calling me an ******* and telling me to **** off. Your feelings to me dont mean a whole lot when you obviously dont care how I feel. Ever heard of a two way street? Well... you're on the wrong side of the road pal.

 

Now what are we all going to do these days? Jump off cliffs and get mad at one another about a type of fuel system?

Madmax, yes, Jon did take it personally when you said that to him. I feel you would feel the same way if you were him.

Can we agree not to agree?

 

Hey guys...........Incase you forgot...........We all own 3rd Gen Fbody......................SO if youre going to ****ing argue.............Argue with some mustang owner..................We should be getting along!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

This started about a week ago, not this post. 'Jon' got pissed off for... hell I dont even remember why. Like I said a million times, it wasnt intentional or planned or anything. I got some email from him entitled 'real funny' in which he told me off much like the posts here, called me an *******, and said he was leaving and not going to be a moderator anymore. I spent about 5 minutes trying to figure out what he was mad about. In talking to Ed, he sent the same email to Ed. So now he comes back to make personal attacks... talk about acting like a grown up. I almost thought he was mature, but has proven me wrong.

 

Wow, 99mph in a C4 vette. You're kidding JP. Or was the funny part suypposed to be that i said that low 142/high 13s is where TBI breaks down. Thank you once again for demonstrating that you cannot read, and that TBI cannot go faster than high 13s without way too much money and a million years of PROM burning experience.

Bort runs 99mph in a 305. With exhaust manifolds.

 

I will say this. ALL forms of fuel systems have potential. I know everyone has personal opinions about everything. I also know that proving things are just as important.
I've never run a 1/4 mile. I will take my car to be dynoed at D-Tech here in Las Vegas. I was going to do it last Saturday, but the brake on the dyno there was bad, and they are fixing it now.
The price for the dyno is inexpensive, and yes I will do it. I can tell you the honest numbers, and even scan the dyno sheet.
I do expect around 310 HP at the flywheel which roughly translates to about 250+ RWHP. I'm hoping to achieve that. I may exceed it, or fall behind it.
The crummy part about my engine is that I am still using the stock manifolds from my old 305, and that is robbing me of horsepower right there.
I was going to have the headers put on during the swap, but the mechanic would not do it.
So I got stuck with the stock manifolds. I still have the headers in the box! (grin) I just need to find a place that will do them for a good price. At least I will have a dyno before my headers are done to see what kind of improvement that will make.
I do have the stock torque converter and have the stock 2.73 open rear end. I hate the gears, but eventually I will do them and the speedometer when I can afford to do so.
I won't talk trash. I will tell the truth. Unfortunately, there are those that kind of stretch their claims above and beyond what their vehicles actually do. I am not one of them.
