BB Crank Pulley

[Bob Nossal]

Did Mopar start using equally spaced 6 bolt patterns for the crank pulley beginning in 1972? I have a 1972 440HP engine.

My 75 440 had them with one larger space.. between the bolts. Not sure if that helps you or not.

My 68 has the "Gap" pattern!

I just "moved" the hole over a smidgeon! That close to the center of rotation won't
matter a hoot.
