Back to the drawing board... stock low dollar 360

what pulleys are you using? could get a spare alternator with the 5" pulley and the small crank one for track use only.
I'm using the factory steel single groove pulleys. I could go to the small crank pulley for sure, and I may. As far as the 5" alternator pulley with the small crank, I really don't want to have a "track" set up as I race the car as I drive it the hour to get to the track.
