Top Quality Early Style 1600 pump. This is the only pump we know of that fits the 65-67 3-main engine correctly:
Shaft does not protrude thru the metal 4-blade fan- no need to drill your OEM metal fan, LOL
Short stud mount for early 3-main 1500 and 1600
Top Quality Aluminum Pump - MIJ - replace that tired old cast iron pump!
Careful what you buy on Ebay, there is all kinds of incorrect H20 pumps out there!
Direct bolt on. Stud change not required which is typically a nightmare!
Note: these are custom built to order_typically ship in one week.
