Just really bored.

At least I got your attention. You have a cool car, you auto-x, you've been a member here forever.

Just sort of surprised how you wouldn't post up any tech help in this thread, only what really reads as insults.

 

I know I know. I am not a very good advice giver. I was just trying to say that I would think his money would go better somewhere else then into his LG4 and then it got all crazy after that. Many apoligizes.

 

The thing is, the cost to rebuild a 305 or 350 is the same. Its actually cheaper to build a 350. I dont understand why you bring up the zz572 when talking about simple small block engines. granted its easier to just use the 305, but you could spend the same amount of $$$ as the blower costs and have a FASTER 350 n/a.

 

whats stupid is, we're not talking about rebuilding anything.

just tossing on a blower to a stock motor.


later on he can stick any motor he wants under it.

 

And to back my claim, I would be a significant amount of money that a 10:1, vortec headed 350 with a hyd. flat tappet camshaft would annhilate an LG4 with a 144 blower on it. My car runs 12.4's at 110 on street tires, PonyKiller's car is in the 11's with a similar vortec headed 350. Its not expensive to build a 350, especially since vortec heads are a dime a dozen nowadays.

 

I edited my post because I realized it sounded different than what I was trying to say.

 

whats your cars weight

power is power is power, the 144 charger is good to about 500 ponies, if he puts it on his 305 now, just for kicks, runs the **** out of it for a year, until it dies, then puts a 350 under it, he is at the 500hp mark, with more torque than most drivers should have at their disposal, and he got 1year of fun time on his 305.

 

i think 500 is a lil optimistic.... closer to 450.... but thats still 450 at the wheels with a mild unquestionably streetable motor. you cant beat that.

 

Withe me in it and a full tank of gas race weight is just under 3300 pounds. My car is not set up for drag racing. Stock coil 82 springs, stock shocks, battery in the front, iron heads in the front. Vortec headed 350 combos are known to make 440 horsepower with untouched heads. Not saying mine does, but I think you will be hard pressed to make a stock head, stock cam LG4 with a blower more than double its power output.

 

And for the record, in a year's time after having fun with his much faster n/a 350, he can put a 150 shot of juice on the motor and be making upwards of 550-575 horsepower, and not be limited by a blower that is now too small for a well built 350.

 

If any of you guys serch for BADDEST305, he had a 11's 305, which is now sportin a 434 ci sbc runnin mid 10's. also Misterjuice has a 12's 305 with a vortech blower ( i think its vortech), stock bottem end and stock heads and valve train, he has edelbrock intake and runners , stock tpi plenum. stock T-5 (from what he told me), slp loudmouth, edelbrock headers and i think 3.42 rear end stock. he dtill has the car and its still breathin.

im probably goin to build up my 305 for the time being , until ive saved up enuff to do a 383 with single t61 turbo and holley stealth ram. by how much money im puttin aside ill have enuff by next year


on topic: i think the main restrictions if you put a blower on a 305 are the heads, cam, and exuast. just change the cam while doin the blower and also if your up to the task pull the heads and do alittle portin and polishin, then get some edelbrock headers and a full catback and the car should move pretty damn good. until you change the torque converter and gears.

my 2 cents

 

I should mention that I won't use a nitrous system on any engine, 305 or 350 or 572. Nothing against nitrous or the guys that use it, but it's just not my thing.

 

I see alot of you guys saying he should add headers, cam etc etc with the blower. He never said anything about doing that stuff. He said all that stuff would stay stock. He'd have to go out and spend another 400-450 on a new hood and then get that painted just to fit the blower. It would add what? 75 hp for 1400 or so bucks? Why not just add a nos kit for cheaper and hit it with a 100 shot? If you dont' like nos then fine. Buy a 350 block for 100 bucks. Spend another 100 cleaning it up. Buy a rebuilt kit from northern autoparts for 200-400 bucks. Wow you just built a 350 for half the money of the blower and it'll be just as quick...

and why do people talk about a 305 engine being a sleeper? NO F BODY CAR CAN BE A SLEEPER! well maybe... if you slipped a nice quiet turbo v6 in it. How do people consider a camaro or firebird a sleeper car when they're known to be fast and everybody knows that?

 

lol, tons of Fbodys can be sleepers...


but want to know the secret to a real 305 sleeper engine?


get a 400sbc, paint it stock black, and call it a 305. :lala:

 

Hey Travis, in your engine description, you cant have a 3/4 race cam without pop up pistons

 

I've been reading this post, and I have to admit...I'm starting to think about one of these things for my 305. So now I've got a few questions. Looking at the Holley/Weiand website, they've got a 144 Pro-Street blower (pn 7740-1) listed as low profile. How close to fitting under the hood will this thing be? Does this thing have pre-87 intake bolt angles (to fit my Al L98heads)? Will it work okay with a Crane 2032HR cam, or should I get a blower specific one? If so, which one? What torque convertor for my 700R4 and 3.73 gears? Will it work with my Road Demon 625cfm VS carburetor? I think that's about it for questions at the moment.

 

fixed.

with a edelbrock carb on it, and no aircleaner it should JUST wont clear the camaro hood by a fraction of a inch. so you need a cowl hood to really use it. a drop base aircleaner and 3" element would work with a 2.5" cowl... if you get a good drop base, you could even use a 4-5" element...

you can get them pre-87, post87, or both (oval holes with adapters for post 87)

it will work with any cam, athough of course you get better results when you match parts.... you're making more TQ so you wont need quite as much converter... the rpad demon carb will work fine, but with a roots blower, its like a bigger motor, so a bigger carb wont hurt it at all.. if i had the choice, i wouldnt go smaller then a 750. but if you already have a carb, dont bother changing it.

 

yeah i'm sure a beefed up 305, a 350 or a sbc 400 would work real good as a sleeper. Maybe if you found some **** that had their system up loud enough that they couldn't hear the exhaust...

a sleeper to me is a car that shouldn't be fast but it is. like the guy that races at the track i race at. he has an 87 GN motor in a newer caddy and it runs 11's. now THAT is a sleeper to me.

 

between the glasspack in the I pipe and the big muffler, i can make a solid cam 502 big block whisper quiet... noise has nothing to do with it. you can make anything quiet and still flow if you want to........


as far as your def, do factory freaks count? if so, i know of a 2.73 rear, stock internal 99 camaro that runs 11s.

what about cars that looks slow, sound slow, and everyone expects to be slow, but they turn quick times? if thats it, then i know a S10 blazer, a S10 pickup and a toyota truck that all turn low LOW 1/8th mile times.. ( no local 1/4 )

theres more then one kind of sleeper. my def is, a car that goes faster then it looks.... kinda like a anti r!cer... lol.

 

Around here, no one expects a 3rd gen to have any *****. You'll get honda's revving and playing with you at every intersection… you could get races with just about anything, even if it's "loud and idles rough."

As far as the 400… The balancer/front cover will tip off most people with a clue.

Is it still a sleeper with bogarts on it?

 

same here, and in texas, and in Mass, and in everywhere inbetween.

somewhat. athough the blower noise is a dead giveaway.


thats what this is for:

 

So where exactly is Cash… from that "everybody knows they're fast?" High school?

(sorry, it slipped out)

heh, can't really hear that at idle and light throttle. That was fixed by putting long tubes, 3" race magnums and turn downs on it. It's not that it's loud, but low, like thumping your chest low.

I like the fact that the monkey bars disappear into the background on it (they're painted hammertone grey and sorta look like they belong even if you're staring right at them).

A shiny, SFI approved balancer is going to make me believe that either the guy telling me that the car is "a stock 305" is either full of **** or a complete dumbass… usually pretty easy to tell which.

 

heh, hard to tell from the pic, but thats not a balancer.. its one of the cheap, cheezy covers that slips over it.


a lil grease and dust and it wont look all too special.

 

Granted, you could get ahold of a 350 engine complete for 100 bucks. Though the ones I've heard of at that price will be in need of a rebuild.

How much machine work could you get done for 100? You say 100 bucks for cleaning it up. If bores aren't worn, that'd probably be okay, just do a hot tank and magnaflux.

But I'm in the southeast; stuff rusts quickly here with all the humidity. An engine out of a junkyard is gonna be rusted, including the cylinder surfaces (this happend to my dad's Firebird which sat out, after a year or so).

So, most used engines I could get would require machine work. Boring the cylinders, honing with torque plate, possibly an align hone of the crank saddles/caps. I'd also want the cylinder heads hot tanked. I probably wouldn't want to use a machine shop that only charged 100 dollars for that work. A bad align hone turns an engine into scrap.

After the engine is bored, I'd need .030 over pistons, new, in that engine rebuild kit. Using the stock cam wouldn't help the power any; a Summit replacement is still apx. 80 bucks.

The cylinder heads will suck for making power. I could port them, then get a three angle valve job. The bigger cam would require machining the spring seats for bigger springs, cutting down the valve guides for clearance. More machine shop expense. Not to mention time involved for myself to do the porting.

Given the time and expenses involved in rebuilding a junkyard motor, I'd go with a crate engine hands down. If I'm going to build my own engine as a personal project, it wouldn't be because it's the economical choice. It'd be for fun, and I wouldn't be cutting corners anywhere on the quality, therefore it would be more expensive.

Is it possible to rebuild a junkyard motor for 600 bucks? Probably, but it's nothing I'd want to sink time and money into.

 

Heh, it's possible to do it if you _have_ to and get lucky. I can think of one that we got the engine for $250, pulled it apart, ball honed the cylinders, gave it new rings and bearings (the bearings looked good but the plastigauge didn't give happy numbers), Slapped it back together and it's been running low 11's/high 10's for 8 years now (about 50-75passes a year + 3-6K street miles/year).

 

I think its a decent idea if your engine isn't beat to hell, just make sure you upgrade the exhaust and get a cowl hood.

Anybody know how long of an install this would be or how much money in labor?

Has anyone here added this supercharger to a 305?

 

Hahaha, I LOVE this board. You know what, the hell with timeslips if you bolt a roots blower to any small block engine in the street you are "almost" untouchable. Nothing absolutely nothing (save nitrous) gives you such a hard kick in the *** than a roots blower. and most nitrous kits are engaged at a higher rpm for safety sake. A blower is imediate. Something ive found out is that on the street you are at a certain speed and most of the time if you are not in the right band for your engine you "WILL" lose. you have no compromises in my personal opinion with a blower "on the street". It there now no waiting. I love blowers specially 6-71s :-)

 

Hmm. Didn't know you could hold boost at low rpms.

 

Why do u have to go to a junk yard to get a 350 block? All you gotta do is look around online or talk to some local race friends. There are TONS of good 350 blocks running around. Just have to look. And there cheap to and aren't rusted to ****.

 

good luck looking at my balancer. it's a sbc 400 but, it has all the stock factory stuff on my car so what little spots you see look just the same

 

It's all bull arguments about this being better than that, and so on. The bottom line is that it's a GOOD idea to slap a blower on your 305, and not be stuck with 305 only specific parts.

Why? use it up first, THEN a 350. And that's pure economic's.
I Say GO for it!

 

I had a real hard time with my LG4, but with the TBI block you have the roller cam and such right? I know the TBI 305 and the TBI 350 weren't all that different in power, as I know a kid in town with a 89 'maro with a 1991 Blazer TBI 350 in it... really not any different than my friend's TBI 305!


I'll take any of you guys on with my minivan Lookin at 13's soon! (2.5 turbo pumping more torque than my 305 TPI )

 

we had one of the local guys here show up at our f-body club dyno last year, he run 12 flat in his mini-van, running 26psi.

 

Yah, I'm currently running 12psi, as I need to build the motor first lol (218000 miles)


So what's the verdict? Going to get the blower?
