I like the Stewart iron water pump ("stage 1"). That's what I have on mine now. The two-row aluminum radiator made much more difference in cooling than the water pump, and I wasn't happy with the cooling system's performance in Texas summer heat until putting in the big radiator. The Stewart iron pump is a safe bet, but any new one from the parts store will be fine as well for a street car.
