What are you looking for? Stock size, underdrive, how many grooves?
March performance makes pulley sets.

I think I have a 4-groove lower pulley from a MARCH kit laying around here?

I just ordered a whole serpentine setup from www.cvfracing.com - looks identical to the March and a little bit cheaper.

I used a March crank pulley. At 6 1/4" it is a little smaller than stock which is ~7 1/4". My warmed up engine idles and redlines higher than stock so the slightly smaller pulley puts belt and accessory speeds about right where they need to be.
