wrench87 You left out the magic words, solids, SBC, and 500cfm 2-barrel,which heads are the only thing missing. You could run that 500cfm on your motor and make good power to.
Rick L. Ps there is a formula that gives you an all around number for carb cfm. 90% of the time this works pretty well. The biggest carbs I have ever run are twin 650 DP holleys, biggest single is a 780 with an 830 or 850 base. Anything more was a waste, burnt more gas and had less responce to driving or racing. Did we win many races NO but spent alot less timing screwing around with the carb, and working on the suspension and handling. IMO it's still about torque and getting all of it to the tires and ground and have it hook and haul. I am building a 498 motor with 4.375 crank, 6.7 rods, and 4.280 bore. 3 of the fastest running cobras are running under square motors. More stroke, less bore. Less rpms needed too. Sounds like longer life of the motor. Rick L.
