Vacuum pump

[mytmouz]

I am acquiring the parts for a vacuum pump for my sbc. This will be my first one, so I am looking for some advice. I am pretty much down to needing a mandrel. What would be a good one to run? I will need 2 pulleys on mine, one for the alt. and one for the pump. The alt. one is about 4 inches from the balancer now...

The only one I have used is a BLP mandrel. It works well and I have no complaints.

If you're going to a gilmer belt drive type pulley, then good viberations sells the enderle mandrels for about $35.00 each, but you will have to come up with the pulleys and belts. They have 2 different styles of mandrels.

I'm not sure on the pulley. The pump has a v belt pulley on it, so I was leaning towards a v to keep keep the costs down. Opinions?

If you can live with a 5.450 dia crank pulley you can buy this set cheap. I realize you don't need the water pump pulley, but the whole package is cheap.
