I need to know what the center to center measurement on the 7.65" crank pulley is that procharger uses. Also they only use 3 bolts to mount the pulley to the balance, correct?

If someone has one laying around and could measure it for me i would appreciate it.

It does bolt on using three bolts, I don't have one in front of me though to give you the measurement. Hopefully someone chimes in. Bob

your best bet may be to call ATI products. they have live customer service reps. mine is on the car in the shop 30 miles away.

When you say "center to center", are you wanting the distance between the bolt holes?

Please tell me you are going to make an 8" crank pulley for these cars?

Nope wanted to 100% verify the crank pulley would mount to power bond balancer.

would a 8" crank pulley fit on an f body?

I have never found any balancer other than an ATI Performance Products to fit, as that is what ProCharger used to design their crank pulley.

An 8 inch crank pulley will indeed fit, years ago we had a one inch oversize one (8.65) made for us for a customer's car back at the old shop. Bob

Bob,
Got any pics or more info on that pulley?

No I don't. It was years ago when we were attempting to max out a D-1SC with the stock J Bracket. We figured that if we made the crank pulley larger we would end up with a larger pulley on the head unit and get more belt wrap. It worked to a degree we were able to get 16 psi of boost but we had the belt tension cranked really tight. If you use the SDCE or the Aster bracket, a larger crank pulley really shouldn't be needed.
