Im building a 88 GTA and my goal is mid 11s and a daily driver. I have SLP runners that came with the car and i was wondering is the stock upper and lower intakes worth porting or should i step up to something different if so, what? Are the alum vette heads worth buying and porting or should i jus go with an aftermarket set because i get my port work done free. Last but not least the cam i want something i can hear but not affect the reliabity and how big of injecters should i use? Is their any good tuning shops that has been used by any of the members around the southeast Tn area? The main reason i want to build this is to show my dad and his buddys is that u can have a fast fuel injected car since the only thing you can get out of them is put a carb on it but i have a 69 nova with a 406 so i want something different. Thanks

There is so much info on this site about this exact same topic try and first and see what you come up with, if by then you cant find what you are looking for ( which wont happen with this topic becasue there are so many proving combos) then ask. Good luck

C'mon, don't just say "search" and not offer the guy any ideas on what to look for.

banksGTA how much do you know about cars and especially TPI engines? You can definitely upgrade a TPI motor to make it really mean. How much money do you want to spend? Some parts don't work well past stock HP levels. For instance, stock rear end will handle 300 hp and can be built to withstand 400 hp for around $1,000. Or you can drop $2,400 on an aftermarket rear end that will handle anything. Similar with transmission. I bring this since I believe that you will need a 383 engine to mid 11's and that possibly a TPI intake (unless maybe a FIRST unit) will not get you there. Might need a different type (stealth ram).

Here is a link to a good article showing different intakes on a healthy 383 with good cam and aluminum heads. TPI can make power but it will be in typical rpm ranges. Don't build a TPI motor and through lots of gear and stall at it. Let us know so we can help you out.

lol I just got most of my parts for a 350 I am rebuilding but before that i had to search through tons of post like this

Are you trying to keep the tpi? have you thought about switching intakes to a hsr or miniram

If you can do a 383 and a short runner intake, go for it.
Else, its going to be rather difficult to get mid 11's and daily driver out of a 350.

Since the thread title is heads/cam/intake, i take it you have a L98 and dont wish to change that at this time?

If so, its possible to get mid 11's. AFR 195's, miniram/HSR, and a big cam will get there with alot of gear and converter.

Ported L98 vette heads MAY do it. You can get 250-260cfm out of those heads which is enough to get into the 11's with a launch. After you pay for porting and refurbishing, it may be better to just get a set of AFR's or similar 195cc heads. You will need rpm to get 11 second power out of the 350.

L98's with the 58cc chamber will bump compression up which is helpful. If stock shortblock, i'd recommend shave down the AFR's or aftermarket heads from 64cc to 58-60cc if you can.

My 383 HSR motor was very streetable but pretty aggressive and ran 11.4-11.5's without much difficulty. mid 1.5 60 fts on 3.42 gear and 3600 stall. 400whp. That was a 11 to 1 compression AFR 195 headed 230/245 cam with .600+ lift and HSR

There are guys making 375-400whp on stock shortblocks with heads/cam, so its possible. The torque wont be as much as a 383 so the gear/converter will need to make up for it.

I dont see TPI making it without extensively modding the base with moving injector ports, raising the roof and increasing cross sectional area like the california guys are doing. That will give you the flow and rpm range with heavily siamesed SLP's but its the more time consuming/expensive route to take. Those guys are making the power for 11's but havent been running the ET's yet.

Sorry for no response i've been out of town but i do thank you all for your imput and i have searched till it feels like it'll never end. Well ive decided the car really is to nice to be hot rodding like i planned since the build sheet looks endless with all the options on it. My question now is what is a good cam to use that wont affect my computer but will be alittle more then stock and it does have slp runners and slp cold air intake and a Gale Banks full exhaust system. Thanks again for all the help and (Orr89RocZ is that car forsale?)

Would a LT4 cam work for what im looking for?

Look at you takin' charge!

LT4 hotcam is a nice cam, but there are better cams these days. Im my opinion, do what you want, within your means. The LT4 hotcam was what I wanted for years, but after some research I ended up going with something a little newer, the LT4HC is almost 20 years old now

you'd have a difficult time getting into the 11's with the hotcam. Considering something abit larger

I jus want something a bit over stock that i dont have to mess with the computer because im jus going to use it has a DD instead of trying to reach the 11s. Whats a good cam that the computer wouldnt have to be tuned for?

I have a ZZ4 cam in mine with no tune. I won't say a tune wouldn't add power, but I have no driveability issues whatsoever. It too is older tech, but they can be had pretty cheap in the classifieds and on ebay as takeouts. If you're gonna go new, look into the comp cam extreme energy line. Call them. They'll be happy to help, and they know there stuff.

Cam swaps are pretty much considered hot-rodding though. I say either do it or don't, but don't go halfway.
