Any suggestions where to find a 3-groove crank pulley to fit an RB engine with a ATI Super Damper. Stock pulley is 7 1/4" dia. 3 3/4" deep. Belt grooves don't line up. Need a pulley 7 1/4" dia. 3 3/8" deep. Billet would be ok as long as it can be machined and still have enough meat left to withstand 6200 rpm blasts.
