He looks at the car and tells me my carb is undersized. I have a Holley 600 and he says I need to up to an Avenger 770. Anyone agree with that??
If your intake is an open plenum single plane, then I would guess the 600 may be fine, best. If you have a dual plane intake, then you may benefit from a slightly larger carb, i.e. 750.
