Road to 500 Rwhp
Honestly, those would be better asked of CARTEK. The heads are 243 castings, so I am not sure how big you can even go with them as far as runner volume before you loose usibility on a stock bottom end motor.
I never had a problem with bottom end torque, but then again, I don't need power below 4500 RPM. I launch the car at 6500 and shift at 7000, what it does below those levels, does not matter to me. Streetability was never comprimised, I can start out in 3rd gear up hill and the car will just go. I can get the car moving up to about 40mph w/o giving it ANY throttle, simply by shifting up in gear at 900rpm. Here is a dyno graph:
I believe I was told the compression is along the lines of 11.25:1 or so. As far as the piston comming out of the bore, its a factory assembled stock bottom end LS1, how much does the piston comes out on a stock motor?

welll kinda hard to see your point when you are just posting links contrary to everything. you can find a vid or write up to contadict anything, doesnt mean its the WHOLE truth
Not sure which post/porter you are refering to.
you should read what I posted. Thats quoted directly from max at cartek.
I think you shop bashers have scared away the original poster. Let's keep this thread technical or it's going to be closed.
