  • Can I put a blower on this motor

    Asked by: Out law 32
    This engine is not designed or intended for a power adder, if one were used it would void our engine warranty.

    Is this a Gen 7 496 block or a 454 with stroker and overbore?

    Asked by: n8mn
    Currently I am showing that we are using the early style 454 blocks to build off of that have a 2 piece rear main seal. This would not use the Gen 7 block.

    For twin engine setups can this engine be obtained with L/H rotation?

    Asked by: Rhodtpr
    The MBP series engines are not available in reverse rotation.
