ok, right now i have the following:

block - 355, mild cam 424in lift; 305 heads (1.84in valves)
intake system - TPI, stock MAF
fuel - SLP LS1 injectors (up to 28lbs/hr)

my question is, if i were to go with the following stystem, what would i have to change in my setup for everything to work correctly?

block - same, but with 500 lift cam, and decent flowing heads (2.02in valves)
intake system - (TPIS base and runners), stock maf
fuel - same

would i have to change my maf??? or anything else? (other than the chip, that is obvious)

ps.
if i do have to change anything, please let me know where i can find the new item! thanks!!!

 

Hey fellow long Islander!!, Just a quick question what type of heads exactly, are you going to be using?

 

Also, i dont see why you would have to change your maf. I think it should run fine stock especially since your going to change your prom chip.Are the screens removed on the maf sensor you have now?

 

no, they arent removed at all. the sensor is actually brand new as for the heads, ill probably be going with something along the lines of an edelbrock performer, or equivalent... unless you have any suggestions

 

You may want to add an adjustable fuel pressure regulator so you can get the most out of your injectors.

 

Make sure the springs can handle the lift and get an AFPR. A larger MAF would not hurt. Make sure you do the free mods for the MAF.

 

yah, ill prob leave the maf alone considering the mods arent really worth the risk, since i drive the car 24/7. ill probably end up getting an AFPR if i cant make the car run rich enough just with the chip.

anyway, can you guys think of ANYTHING else that i would have to change for this to work correctly???? and when i say anything, i mean ANYTHING lol thanks! also keep suggestions comming on cam/heads, b/c i need some. im probably going with a hydraulic roller this time around currently im using a hydraulic flat tappet.

 

You have an 89 formula right? Shouldnt your engine be a hydraulic roller stock? Also if your gonna go with a new cam and head set up maybe you should get some 1.6 roller rockers as well. They can raise the gross lift by .030, just another suggestion.

 

my engine is not stock, it used to be a 305TPI, i pulled out the 305 block and threw in a 350 with a hydraulic flat tappet cam, and kept my 305 heads b/c i couldnt afford new heads at the time. i just need suggestions on how big of a cam i should run, and what heads would match up with the TPIS base and runners intake system, and if i HAVE TO change my MAF. thanks again guys

 

I think I read somewhere on here that if you put in a 350 block and 305 heads, you're robbing you engine of horsepower. Anywho, I think I would invest in 350 heads of some kind,even if they're stock.

And please..don't do any of that "free mod" shyte to your MAF. I have read over and again how it is nothing but a bad idea, not matter how wonderful the short term gain. If you're going to open up you air intake, I'd say go with a Wells MAF; It can flow more air than stock and I'm going to order one in conjunction with a new K&N cone filer sans air box. Also, you may wanna put a 52mm TB on. And (you said ANY ideas) since you're gonna get a new runner/base, you may wanna remove those stupid "blocks" just inside your plenum.

I'm getting ready to do an air-filter to intake manifold upgrade with those mods and more.

Good luck....

----No, some of the 305 heads flow better than the 350 heads. 305 heads will also raise your compression on a 350. That can be good. I believe the 416's and 081's are 305 heads.


And please..don't do any of that "free mod" shyte to your MAF. I have read over and again how it is nothing but a bad idea,
----Says who? how does it "hurt?" You are not messing with the air metering.

Wells MAF=AutoZone. AutoZone in particular is not to great of a "speed shop

you may wanna put a 52mm TB on.
---No. It would be a waste of money at this point. You need to read the stickies about this. I would only get a 52mm if it was a killer deal, lide $50.

 

tibo, i completely agree with everything you just said about that other guys comments. i know that my heads are pretty good, they just need bigger valves. the 1.84's are whats really robbing me. if i had 2.02's, and ported them, i've heard they can flow better than vortecs, and since i run 93 octane b/c my compression is 9.75:1, i can run a very high advance. im probably gonna end up throwing the TPIS system on my intake and thats it for now

 

True. If you have read the Vizard's book on small block chevy heads you have seen the difference that adding bigger valves can make. It helps. He has published many before and after charts of everything he does. Go for the bigger valves. Make sure you unshroud though.

 

Well Tibo, I'm willing to bet that you're one of the folks who likes to tell people to do a search before answering a question. So, Tibo, if YOU do a search you will find a lot of readers of this very forum who discourage the descreening and gutting of the MAF. You can find your own evidence. Also, if you do another search of the Wells MAF, you will find another positive majority of the folks who like/use the Wells MAF. I wasn't advocating AZ as a speed shop, as you apparently were. The 52mm TB IS a good idea, assuming you read my entire post. I don't believe I said anything like "go buy a car, put a 52 on and you'll run 11's"

I don't claim to know everything, but I do stand by what I have researched.

 

There are over 42,000 members on these message boards. Many people believe many things. That is why stupid things are always being debated on these boards, and then repeated. You can do a search and come up with anything you want to support any idea you can come up with about a SBC or f-body. It does not sound to me like he is going to have a large cam, high flowing intake or expensive wild flowing heads needed to make a "bigger throttle body" argument. I did not say AutoZone was a speed shop, I said it wasn't. It is a good place to get Fel-Pro gaskets and other misc. stuff, that's it. You only have 32 posts, you are a newbie. If someone comes along and critiques your post, such as I did, you need to take it less seriously. It is not a personal attack and should not be retaliated against as if it were. Many more people will critique or argue your post in the future.

 

 

lol, well after that little debate....

do you guys think going with the TPIS runners and base is overkill for my setup right now??? or do you think it would help?

also, head-wise.... how do i know if a pair of heads is going to match up with my intake base nicely???

 

I think the best thing to do is to get Vortec heads (real vortecs) a vortec TPI base from scoggin-dickey, and slp runners. I say slp runners because they polish very nicly! But ASand M are better. There are a good number of people running that combo with good times. If you wanted to spend less money on heads, go with a set of ported l98's. If you can spend more money, go with a set of dart iron eagles or and aluminum head. Any brand name aftermarket aluminum head is good nowadays. Just flow a little more. I myself went with TFS' kenny D.'s. I am porting them now.

 

Im finishing up my 350 vortec sdpc vortec base conversion from 305 carbed. I also got a set of SLP runners and i dont really care if they are or arent a big gain on power or get higher rpms, they look really cool on the engine. Also id just worry about getting the heads and cam matched up first then after you got it running the way you like then get the runners and the throttle body you want. Those are just easy to do bolt ons anyway, its the engine, heads, cam and headers you wanna focus on the most right now. Also if your going to go with vortecs be sure to have the valve guides machined for clearance if your going with a cam over .450 inch which it sounds like you are.

 

yah, that all sounds good, but if i just bought the TPIS base and runners right now, and threw it on my motor, just to get that done, would that make my car run like crap? im only saying it b/c right now i cant really change the cam/heads, im waiting for the summer to do that. but if i can just bolt on the runners and the base now, would that hurt? or help me with my 305 heads....

 

It would help, but you would not be able to run the vortec heads, they have a different bolt angle. Vortec77- have you run the car or driven it yet?

 

well whatver, that doesnt really matter. im not decided on the heads that im gonna get yet, im probbaly gonna stick with my 305 heads for a little while until the summer

 

No not yet, getting the small stupid stuff done, ya know vacuum hoses, battery, coolant hose. Im gonna fire her up soon though, I hope i dont have any problems getting her running. I hate when you try to move foward and you end up taking 2 steps back just to take 1 step foward.

 

yah man, i went through that last summer when i put the 350 to replace the 305 in my car. just go slow, make sure you have everything before you start doing ANYTHING b/c the worst thing is being in the middle of something and being like AHHHH i dont have a *******ing intake gasket! or something stupid like that. anyway, best of luck man!

 

Thanks,
