Hi, All-
I am pulling together some details to finish out a 440 (six-pack!) for my 66 Charger. I did some wheelin' and dealin' with a buddy and have a freshly rebuilt (1000 miles on it) 440 with ported / polished heads, forged crank...lots of goodies with an estimated 450 HP. This is a 1969 motor.
I have added a six-pack intake, a set of fabricated valve covers and am now working to add pulleys.
I bought a set of pulleys off of eBay for $40. (Crank and water pump, non AC, big block Mopar) Received them...media blasted them and painted them. Upon trying to install the pulleys, the holes do not line up.
I believe the crank pulley may be an "offset" bolt pattern, pre-1972 big block? Though my motor is a 1969, it has an aftermarket vibration dampener to match the balanced forged crank.
So...my question is: Do aftermarket dampeners have a higher chance of having a symmetrical bolt pattern?
I think I just need to bite the bullet and get a symmetrical bolt pattern crank pulley for non AC motors. Found one on 440 source that may work. Anyone interested in a freshly painted non-symetrical crank pulley? :rolling:
Here's a photo of what I have so far.
