I have a 36 LB 21 stud engine that had water blowing out when pushing it & getting warm one grades. Sent two nos pumps to skip for his touch. Got them Back & installed them along with the 3# check valve. Runs good & no blowout the radiator cap when pushing it or up a grade. This is a fairly fresh rebuild by Furtado (now deceased) & cleaned radiator. Only wishes are better gearing as with the 4:11s I seldom use 1st gear. Better gas mileage would be good with higher gear as then I would make longer trips.
The skinny little air filter is history in the pic.
