was wondering if you checked to see if you have a zero deck?
Having a zero deck will decrease the chance on detonation, it will run better period.
"Proper quench creates turbulence in the combustion chamber, theoretically pushing the mixture toward the spark plug and reducing the possibility of unburned gases at the completion of the combustion cycle, which can play a significant role in reducing detonation and even exhaust emissions.
Quench should be as tight as possible without the piston actually contacting the head. This, in turn, is largely dependent on the type of connecting rods and the engine’s peak rpm. A good rule of thumb is that you can run as little as 0.038 to 0.043 inch with steel connecting rods. Steel-rod street engines that don’t see the far side of 6,000 rpm may even be able to shave this to as close as 0.032 inch."
A 3/8 fuel line is fine. If you really want 600 + HP, step up to a 1/2" What fuel pump are you using & what psi does it put out? Need a quick run down of what regulator , pump you are using or going to use.
