Shelby Water Pump Details
I’m looking for a water pump for my 1970 Shelby G.T. 350. The Ford service parts book says the replacement part number is a D3UZ-8501-A pump, but what was the original part number and how do I tell the date code?
Des Plaines, Illinois
Most 351s from 1969 came through with the C8OE-8501-D water pump, although the C8AE-8501-J is identical and may have been installed on some engines in 1969. Ford didn’t stop the production line just because they didn’t have the correct water pump. Trust us, it happened a lot with all manner of parts. Stopping the line had to be a true emergency! If you can find one, go for the C8OE-D. As far as the date code, it was very lightly stamped on the backside on the gasket area, and this stamp was usually lost after the first rebuild, so don’t worry about the date code. The casting number is more important. Good luck in your hunt.
Cobra Oil Pan Fitment
I picked up a Cobra aluminum oil pan at a swap meet. It doesn’t have the dents like my original 1966 289 steel pan. It should fit, right?
Yes, it should fit. The two “dents” on the sides of the oil pan were put there to provide extra clearance for the inner tie-rod ends on the Mustang. The Cobra pan doesn’t have them but you should clear no problem. Just to be on the safe side, turn your steering wheel lock-to-lock and check the clearance to the tie rods. If it looks like they would clear without the indentations, you’re golden. Nice score on the pan too!
