    If your're talking about a reverse rotation pump, you have to remove the serpentine belt set up and use standart rotation pulley set up.The radiator works the same on both.If you're talking a reverse flow LT1 I don't thing you can change without a diferent motor.Bill.

    If you use the factory clutch fan from the reverse flow on the standard rotation pump you swapped to, it will overheat...
    If you think nobody cares, try missing a payment...

    the 350 was a 1991 out of a van[ same as the radiator]

    it is on the engine start up unit right now --no fan on the engine -but big fans blowing thru the radiator

    i have an older style radiator we are changing to tomorrow and trying that out

    it really acts like it does not flow properly thru the radiator --it gets 210 pretty quick--so we shut it down--sometimes in 2 minutes other times it will go 10 minutes before heating up

    by the way --NEW RADIATOR--NEW WATER PUMP-NEW BELT--AND NEW ENGINE BUILD

    ops: ops: :cry: :cry:
