    Default SFI Flexplate by PRW

    I found this while looking thru their catalog. Is it something we could use on our Maggy engines?

    Yes, if you have a 318 or internal balance 360/408, B&M makes an external balance flexplate for the LA and Magnum engines. No one makes a SFI flexplate for the magnum engine with a tone ring, Mopar performance used to offer an SFI flexplate for EFI magnum engines but they have been long since discontinued.

    So, anybody that went internal balance like I did could use this instead of a 318 plate. Cool.

    As long as you don't need the tone ring for the factory crank sensor then you can run that flexplate.

    Doh...You're right! I need the tone ring. Have patience, I'm old and feeble!
