    Do aftermarket 455 aluminum crank and water pump pulleys fit the 350?

    Depending on water pump length they will line up.

    Has anyone done this on the 350. I would love to ditch the factory pulleys when my motor is finished at the machinist/engine builder.

    Thanks, I have dual electric fans so I won’t have any issues.
