engine build

[lozanoa11]

Ok so i want to build an engine to put into a third gen. My original plan was gen I carburated 383 high compression on e-85. Making about 600hp.Well peak numbers arnt important i just wanna run 10's.
Well i got to thinking gas is expensive and alcahol gets crappy gas mileage so mabey ill go fuel injected. I was thinking of useing a lt1 platform for the fuel injection insted of tpi for the higher rpm potential(probaly only 6k or so is all i want).

And then i was wondering am i better off using a gen II block also? Insted of making lt1 heads work with gen I block? But i would want a four bolt main wouldent i? Witch would be lt4 block. Or would a two bolt main be fine? I can find gen I whole engine for like $200 i don't wanna spend alot on a engine that i wont be useing most of.
Is there a stand alone pcm for lt1's or what year pcm's are easyest to tune? I would be doing all the tuneing myself.
Does someone make lt1 headers for third gen's?
And no im not gunna do a ls1 b/c i don't have the money to do a ls1 like i would want to do.
Thanks for your help guys.

A two bolt LT1 block is said to be good to about 6500 rpm. But saying that, I would never spin mine past 6000.

so you wanna make 600hp and run 10s but you can't afford to build a LS1??? Better keep saving IMO.

How much is your budget?

It sounds like you should set some priorities.

Rank these in order of importance...budget...power...reliability...fuel economy...streetability.

And if you want to make anywhere near 600 hp or run 10s, fuel economy should be last...or not even on the list...lol...

no kidding hes gonna need some nice heads lol for 600hp

i dont even have that prolly at the fywheel

600hp NA with a small block is gotta be one bad ass build... even for an LS1 let alone Gen1/2

Here's some problems that I see for your future, because I am currently doing the same project.

Work your way from the back to the front. 600 hp is going to Grenade your rearend instantly unless you run street tires and spin the living hell out of em.
Obviously a stock 700R4 isn't going to last either. Those are by no means cheap to build for that kind of power.
Then your engine.... Joel makes a good point, budget minded and 600 hp is not an easy task. If you're building that kind of power, you're going to spend around 8k on the engine unless you spray it into the 10's.

Another thing... F-bodies are subframe cars. They twist, squeek, rattle and all that good crap because the chassis isn't all too strong. Subframe Connectors, a roll cage, and a whole list of other goodies are needed to get these cars to move in a straight line. Don't forget to beef up the suspension!

Shawn that is the perfect response

[shawnc16]

Why thank you sir.. I do know a thing or two about wasting/making use of my hard earned dollars.


Something that I missed before... You can't put LT1 heads on a GEN I block. LT engines have a reverse cooling system.

honestly ill say this ive always wanted to go real fast and have a fast car but now that i have a decently fast one i dont like it like i thought i would

my car gets a little squirrey at even 60mph, reason im going to something else...

i mean its cool but scary and i dont wanna hurt myself or anyone else

i dont really floor my car becuase of this lol i feather into it

I would build a LS1 for sure, Be much better in the long run, There are tons of combos you could do. I just would recummend a forged bottom end and go from there. You can go with some heads and cam, set ups. Or just build a big C.I. LS1 .. got a web site 4 you to look into..

you have received some good advice in this thread, and ill just extend onto it, I think you need to really look into what you want, have you ever driven a 600 hp car? Im assuming it will be more than you will even like (take supermans car for example). Also considering your last car was a 3.8 camaro this is quite a step up. I reccomend starting out smaller with the car and getting suspension rear end etc like everyone mentioned, and then slowly working the car up the power scale. If you plan on running tens there are many safety parts (Ie. roll cage, driveshaft saftey loop etc..) that you will also need to run at the track.

[JoeliusZ28]

ill second what derek said. Even though my Z28 only has about double the horsepower my 3.8 has, it feels like four times. 600 hp is probably a LOT more than you think.

ok so mabey i shouldent have thrown out the 600 hp number. but i would like to reach 10's even if i have to spray it there. I know that im not just throwing this into a stock body. It will be caged with suspension mods big rear end built trans the whole thing.
I would love to do a lsx build and i am still thinking about it. But i think it would cost me more because i would be doing a big inch n/a build. Im just figureing out my options.
I know thats alot of power but this is not a daily driver this is a drive to the track and a sunday driver.
And i want to just build the engine and throw it in and be done with it as long as nothing breaks.
Idk mabey i should do a lsx and be done ill have to think about it.
All your imput is greatly appreciated.

Ill tell you right now, To build a LT1 with 500+ HP. It will coast ya about the same. to do it right, A ls1 is about the same price... Do the ls1 you'll be much happyer and you will get alot better gass mailage, and be more relible as well. Run a ls1,ls2,ls3 style short block, with a set of good heads, and cam, intake, you will be way happy. she will run very good..

-Dont forget the Transmition, Rear end, and getting it legal to run @ the track..
