Look on e-bay there are lots of different ones to choose from. This is the only one I saw with 2 pulleys on each side though.
I got this motor shipped to my door $57   :P

I haven't gotten an alternator yet.  What would you say is the best one to go with?

The AC Delco alternators from GM cars from the '70's to mid-80's are the easiest to work with as you can easily take them apart to make your wiring changes. In addition, even with the core charge they're cheap. I recently bought one for a '78 Chevette (future H20 vehichle) and it was under $40 from Advance Auto. This is what I intend to use.

I found a westinghouse 8.7A   1725 rpm motor , and a AC Delco alternator. the alternator needs rebuilt, but I was going to open it up anyway ;D. I may need some help on that wiring job .

I got this alternator from my '78 F-150.  Is this perfect or what?   Now I just need to figure out which wire goes where....

thanks hydrocars, I'll get one this week. Try to get 3000 to 3500 at the alternator
