I have an 05 lq4 that I will be installing with a t56 and 8.8 ford rear with either 355 or 373 gears, in my 94 s10 shortbox. I plan on using 1 3/4" lt headers and dual exhaust, an ls6 intake, cia, underdrive pulley and a small custom cam, (probably by Pat G) could a setup like this make 400whp with good driveability and decent mileage? Or should I look at an L92 head and L76 intake top end?
Any info would be appreciated.
I know what you mean about heads, on my camaro I bought Advanced Induction heads and couldn't be happier. I will probably go with the L92 top end. I just wanted to see if I could get where I wanted to be with the stock 317 heads. The truck will be my daily driver, and not see the track much.
Thanks for the input. Are you on s10 forum?
Does anyone have an opinion about making 400whp with the stock 317 heads and a small driveable cam? I'm trying to decide if spending the money on an l92 top end is required to meet my goals. Any input would be appreciated.
freind of mine has stock 03 LQ4,cam only - comp 228/230 cam, vic jr/carb, 1 3/4" headers. engine made 478hp on engine dyno(not wheel hp).
I agree w/justus67 - mill the stock 317's .030" and cam similar to 228/230, and your there. my.02
