New pulley availble for ProCharger users We have a 8.65" DIA 8 rib pulley crank for the F-Body ProCharger systems.
This will allow more boost with a larger head unit pulley increasing belt contact
area and reducing slip.

You can also purchase the pulley from Bob at Brute speed.

I have a SBC on the stand with a ATI balancer and the pulley bolts right up.
It looks like 2 different patterns in the pulley but the larger holes are clearance holes
for the bolts that hold the AC pulley to the back of the LS1 ATI balancer.
The patterns are the same. The main hub on the ATI balancer protrudes out the front about .090 and the back of the pulley has a counter bore that centers the pulley and takes the side loading.
I done a test fit just to see if the front of the SBC and LSX ATI balancer's where the same, and they are.
If you have a ATI balancer on your SBC this pulley will fit our motor.
