I have eliminated the power valve on my 750 dbl. pumper. The 750cfm DP sits on a moderately tweaked 351w. We use the car to cruise and race. I went up 7 jet sizes, and the car runs great with no more PV worries. I am building a 408 stroker for my 73 Bronco, and I will run a Holley, until I can purchase affordablefuelinjection.com's sefi setup. Anyone have any input good or bad regarding the www.AffordableFuelInjection.com SEFI setup? any input is appreciated.
Some good reading about the topic:
