Probably a 4 or 7 lbs cap if it fits the PW radiator neck. If you have not had the radiator rebuilt, putting a pressurized cap on could cause some problems. Pressurized cap just prevents coolant loss from evaporation or by heat surge, doesn't necessarily mean it is required for that engine. I guess the question would be, will the stock radiator cool the additional amount of heat with out it being pressurized ?
