My buddy just got some march v-belt pulleys I think, for his '72 K/5 and they are pretty damn sweet. THe belt that drives the water pump and alternator is like 1 inch wide and ribbed. The power steering belt looks like the regular stock V-belt. His 388 stroker motor used to throw belts all the time with stock pulleys and now it hasn't yet. Anyone tried serpentine or march v-belt pulleys for their short water pump smallblock? I'm looking mainly at the March V-belts for Short Water pump w/ power steering, and without a/c - in the Summit Catalog. Any input would be appriciated.
