Timming Question
My buddy just assembled a D.S.S. super bullet with new cam and performer rpm heads and intake...the problem is the car wont run unless it has at least 18 degrees of btdc and runs best on 24 but gets hot. Any Ideas? Opinions?

Are you sure the cam timing is right? How big is the cam? Not to sound stupid or anything, but I assume you checked the timing with the spout removed?

Just making sure, but do you have the little dot on the cam gear facing down and the crank gear facing up?
It is possible that he has a cam that is too big for the computer, even mass air has it's limits. Murdock |

How big of a cam? Give me some duration numbers (total & @ 0.050"). Also, what's the idle speed you're trying for?
