Yes - I'm looking for a single v-groove pulley set where the water pump pulley has a smaller diameter than the crank pulley. It seems like the only factor overdrive sets were for A/C cars that used huge multi-groove crank pulleys, which I don't need.
I'll look to see if March has a water pump pulley that'll work with a single groove crank pulley. The problem I've encountered is that the single groove crank pulleys I've found are a pretty small diameter.
