    I have a 1975 mav that originally had a 250 i6 and recently I started doing an engine swap with a 1968 302 block. I have all the required parts to make it work but I’m stuck right now trying to figure out if my water pump is reverse flow and if that’s going to impact on my engines cooling capabilities, or if I need to use a different application to make this engine run happy . And quite frankly I am confused as hell .

    Reverse flow are serpentine belt applications that operate pump from back side of belt, didn't exist till mid '80s.

    V belts are all std rotation.

    Pulley bolt pattern is wider on reverse rotation serpentine, std rotation pulley will not bolt up.

    I'm yet to see a '80s T-Bird/Mustang with reverse rotation pump, that did not have a std rotation timing cover.

    There are differences is timing covers for standard & reverse rotation.

    It is not that it is reverse flow - the radiator hose is either drivers or passengers side intake. So the early 302 pump intake (68-69) was on the passenger side.
