The Holley carb that I have is a Holley 0-3310S Vac Sec. Model 4160, 750 CFM, Square Bore, Manual Choke, 4-Barrel, Vacuum, Dual Inlet, Silver

I did not try jetting the carb or changing the power valve knowing the carb needed a 4.5PV. She was also burning a little rich and smoking at idle, but would clear up once warm and I drove the engine about a mile or two.
The main reason I want to change the carb is my engine made more torque and horsepower with a double pumper than the vac. sec. on a dyno.
That might not compare to actual street/strip power, but I want to give the Demon a shot and tune it on a chassis dyno later in the new year.
