    Will a 409 crank w/ a 3.5 in stroke bolt on to a 427 or a 454 block?

    No, crank has wrong dimensions for use in a BBC. 348-409 was a completely different engine family, although the 396-454 Mark IV family has it's "roots" in the 409 engine.

    You can put a 454 crank into a 409 but you have to grind the rear journal down. But putting a 409 into a 454 would be hard to do but it could be done with spacers.

    I'd love to find a 409. If I could, then I'd have to find another 64 Impalla SS !!!!!!!! /forums/images/graemlins/thumb.gif
