where to find a smaller crank pulley?
What car would have a smaller crank pulley for my 351w?
I'm having trouble keeping belts on th alternator. Everything seem aligned properly now and I still keep tossing belts. I even use the "good" belts.(gatorbacks) I was told to use a smaller diameter crank pulley to underdrive the alternator. I just wanted to know what cars would have a smaller pulley. Mine measures 8 inches.

Ford Racing makes aftermarket underdrive pulley sets...
However, if you are throwing belts, then I would think that there is another problem somewhere, if not with alignment, then maybe with the angle of the pulleys, one might not be completely square with the others... |

Re: where to find a smaller crank pulley?
If your set up is as you have it written, then you are not twisting that many RPMs... if you are, you need quite the upgrade at the intake...
Admittedly, I never really pushed much past 7k, but I never had a problem with the belts. |
