    Yeah both of the websites posted are awesome. The first website is more gearing detailed, and the second website has more variety of tools like fuel injectors.

    I believe the front pulley on a 366 and a 454 are NOT interchangeable due to size measurements.

    454 is the same back to 1975 or 1973
    But the motor home engine will have a RV cam in the motor for pulling
