Vacuum pump drive mandrel recommendation
« on: March 13, 2019, 08:32:36 AM »

I'm trying to figure out which mandrel drive I need for my application.
I have a Moroso 22640 and a custom bracket mounting it, due to old big chief style cylinder heads.
It's a BBC with ATI balancer
The pulley on the vacuum pump is 4.750 inches from the flat face of the balancer.
What mandrel would you run?
