Be careful over driving that blower with out a crank suport with that pulley that far out there.
Good luck
Here is the latest pics, fully assembled for hopefulley the last time. Note the blower drive snout, the top pulley is actually installed backward. The snont is Dyers 10.25" long. Usually a AMC uses a 8.25 inch drive with the pulley installed outwards. I wanted the most support on the outer bearing so I reengineered the system so that the blower belt tension is actually behind the outermost bearing.

BTW Fuzz if it only makes 1075 HP with N2O I'll be disappointed.
