Has anyone ever used the aluminum crankshaft pulleys on a small block? My 1968 340 pulley had cracks and I was told they don't make reproduction ones to fit 1968 with a cast iron water pump, water outlet on drivers side, so I was wondering if anyone had any experiences with the aluminum ones like this one
