avenger 670

i have a 355 with vortec heads and a crower cam, 220-226 duration and 462-470 lift.
would a street avenger 670 be a good choice of carb?
would anone know what kind of power that combo would make?? i was thinking 350ish hp

Personally, I don't think the Avenger carbs are a good choice for anything.

Properly supported & tuned, it should make at least 350 HP (gross flywheel).

Holley 650 double pumper, Performer RPM intake, headers, good exhaust.
