I'm currently using 670CFM Street Avenger. I swapped it out for an older Holley 650 with mechanical secondarys. I to bought the 650 used. It was in need of major work as the previous owner plugged the secondary power valve circuit.
I changed to the Street Avenger and could not be happier. It does run a little rich out of the box but not to bad. Gets good marks on performance and reliability.
This sits on top of a 302 motor.
