Obscure Pulley Question
« on: October 01, 2008, 05:38:29 PM »

What is the bolt pattern on a big block mopar crank pulley?

I'm trying to find a 1/4" spacer for my motor plate and all I can find is chevy and ford stuff.  I may have to make one.

S&W sells a ford spacer that has a w/ 4 x 3.31" bolt circle.  I'm curious if this will fit if I just drill new holes.

Watch yourself there...........
A lot of balancers/pulleys had asymmetrical bolt patterns with one hole being offset. I just received (today as a matter of fact) my new fluidamper from 440 Source and it has a symmetrical bolt pattern. I will have to either enlarge the one hole or replace the pulley.
