Man, where have you guys been? PLEASE, call and get a short water pump from us at Patricks! The '55 engine requires the larger diameter pulley to slow the water down! Also, use the '235 fan PLEASE NOT the '216 fan or it will SPIN 190 PERCENT of its capacity! Also, use a 180 degree thermostat and a 4 to 7 pound radiator cap.Also not a bad idea to install an overflow jug or upgrade to 4row desert cooler radiator.Many 6 cylinder websites have reprinted our swap article as to how to do this swap easily.The water pump we sell is a brand new, specially designed short shaft and shallow pulley to clear the radiator.
