don't know on other pullys, but my buddy has ran these GMs on his toy 22re's for years no problems, nice part is they put out like 80a at idleCan you get different pulleys for the GM alt's? I have a couple kicking around but I would be hesitant to run it cause im usually at 4000-5000rpm all day and im sure thats a little too much for that thing.
i would save the money and fab it up myself. 250 seems a little expensive, prolly soesnt even include the alt.:shaking:
