a couple horse on a mild build, not really worth it on anything other then an all out race build
If you change to the ls1 firing order it is easier on the crankshaft and makes the motor smoother.
LS1.....I never heard anyone doing that before, I am not going to get fancy...I am going to stick to basic stuff that works till I get my car figured out. I have a big learning experience ahead of me as soon as I get my car done. But thanks fot the input guys I rep'd ya too.
