I have a lq4 block cleaned and honed ready to assemble. I am planning to run a vortech supercharger in the future so I got the Blower Cam from Bob at Brute Speed. I posted the other day about heads and I got to thinking(prob not a good thing). Bob dynoed a vette that made a lot of hp with not alot of mods. So now I am thinking I need to just make my Lq4 into a ls2 and bam I will have a lot of horsepower. So I need flat top pistons and 64-65cc heads and I will be at the same compression so in theory it should be the same. Now I know most people would rather have the lower compression but I am not planning a lot of boost and if Bobs Vette made a crap ton of hp I should be able to too. Does this sound stupid or will this work? Oh and I found some bare ls3 castings with 64cc chambered so maybe this would be a further bonus? And do I need forged pistons or would the factory ls2 pistons work for half the price? I just need as much hp as possible because I have a baby on the way and you never know when I might have to get diapers in a hurry. Thanks for your guys time!

 

I'm guessing your new infant could care less if your engine has 10.9 or 9.5
compression ratio. Why even waste time changing anything at this point ????
Run the blower at 10 lbs. instead of 8 and the butt-cheek dyno will be very
happy !!!
