I just purchased a Moroso Vacuum Pump and I would like some advise on whose Mandrel drive and crank pulley to purchase. If you would please post your suggested product with the price for said product as well as part numbers. I hope the market has grown in this area as I have only found few companies making these parts.

Really wish I had a CNC machine, I could design and build it myself lol

There aren't very many choices if you're using a Mopar pulley pattern. I have a Moroso mandrel that is new in the box if you're interested.

I switched over to the BB Chevy bolt pattern a few years ago and there are a lot more choices for mandrels. But that requires a new damper.

Jones, Star, Moroso, Aeromotive,CV and GZ are all options.There are also some smaller guys that do custom stuff, but I am doubting your wanting to pay that price.

Like Andy mentions, you'll have a better time with a BBC pattern. That being said, there is enough stuff out there to make a BBM work fine.

i'm buying a GZ pump my self and I think you'll find they have everything you need.

I made this one myself. I made Mopar mandrels for awhile but they were such a slow selling item that I eventually retired the product.

CV products makes some nice stuff. They stack up with various size spacers and pully options.
