    20412 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from I installed b&m's holeshot 2400 in my 1988 Winnebago 454 big block th400 And noticed right away a better idle and excelleration. No problem pulling a trailer up over mountain passes. Seems to be running cooler than with stock converter. If your thinking new converter this is it. Charlie M.

    What gear ratio is recommended with B&M holeshot convertors 2000 & 2400

    Asked by: Purp
    This will depend on the tires size and the camshaft being used. Please refer to the cam information.
