    I have a stock 1968 RR, engine is stock including manifolds. I would like to change out the carb to a new one and have the old one rebuilt and saved for later. What carb is best for my setup and will fit my stock manifold and air cleaner?

    I have been looking at a Holley 670 Street Avenger but do not know if it would work.

    I am running a Holley 750 dual feed on mine. It runs excellent. I wouldn't go any bigger.

    That sound's rite. Any bigger and get wash down due to much un burnt fuel in the cylinder. Hard on the ring's also. Good luck.
