WHat about underdrive pulleys or crankshaft pulleys. My brother did a lot of mods to his Corvette which he uses for racing. I think it was in the low 300's stock and he brought it up to 375HP. The one mod he DIDN'T do which he says he wished he had was install a crankshaft and/or alternator pulley.

My Q is are their any available for the S and would this be a direction to go in???

Thanks.
