    if theirs a BB in it already then a 540 would be no problem..same size on the outside..if theirs a mag motor in it already you can save some money and have the 454 refreshed and add a blower to get close to 600 hp.

    If the 540 has a high rise single plane intake it may not fit. They are a few inches higher than the standard dual plane or HP dual plane manifolds.. Jamie

    If you build a 540, build it with a short deck motor or you will have to change the holes in the transom.
