LQ4 engine

I am new to chevy motors but I have picked up a camaro with a blown engine for cheep and am working on fixing it up. My question is i have got a 6.0 out of a 06 chevy van and was wondering if it was the same as what comes in the silverados and h2s. I was looking and it appears to be the same engine but it is only rated a 300 hp while the others are 325. What is the differance? I saw a article where someone took a lq4 and put l92 heads and a hot cam and bumped th hp up to something like 470 hp is this possible with the 06 van engine? I want to get good hp but need to know what I need to get it. Sorry for the newby questions but like stated before I am new to the chevy engines I am used to working on fords.

Re: LQ4 engine

you might have better luck in the swap forums, you can get it in but it may cost a bit more $

good luck

Re: LQ4 engine

I am not concerned with getting it in. My question is what is the differance between the 6.0 in the van and the 6.0 in the silverado and h2? There is a 25 hp differance and I would like to know why. Is it the sam engine just different intake or something else or is it a completely differnt model engine.

Re: LQ4 engine

most likely its the cam and valvetrain. and/or the intake setup

motors are the same minus those two factors. If your gonna build it anyway it shouldnt matter

also take into consideration if its a roller cam or a flat tappet id say look up the motor specs on like google and compare the two

Re: LQ4 engine

LQ4 should have dished pistons and less compression than the LQ9

Re: LQ4 engine

what is a good setup for the lq4? I would like to keep it fuel injected and would like to get around 450-500hp out of it with out nitrous or a blower. Any sugestions would be helpful.

Re: LQ4 engine

www.ls1tech.com

you can get 482fwhp with just a GMPP hot cam and carb intake with the year 2000 IRON heads. Mill some stock aluminum heads too bump comp to about 10.5 with a hot cam and you'd be looking at 500+ hp maybe more with some good porting.

L92 heads GMPP carb intake and a good cam will get you 550 fwhp. But like xpndbl said ls1tech is the place to be.

GENIII/IV engines are no joke.
