So I like to start with a clean slate on an engine and buy the edelbrocck dist. It is adj mech and vacuum. I set the mech to the most responsive, most power I can get. Then I hook up the vacuum to the manifold port and dial in my advance to just below pinging under load.
This gets me the best throttle response and mileage and no hint of overheating. Never had an issue and my **** always runs better then the guys struggling to cool their engines. Can go on a cruise my car over heats ect.
PV does create heat and burn cleaner. It is less friendly on a street car in my experience. I adj my carb to compensate for the adv drop and have zero bog flop issues.
I'm not sure if I'm disagreeing with you or not. PV is was for emission reasons.
