    Yes, Rick is right, they are measured in OD not ID...
    Actually I blew it. I'm the one who should plead tired. Heater hose is sold in ID.

    My apologies to all.

    On 55 and 56 the lower hose from the heater goes to the higher fitting on the engine, the intake. The upper hose from the heater goes to the lower fitting on the engine, the water pump.

    I posted this last night (IN THE WRONG THREAD!).. so I was tired last night too!

    "Well... let's just agree that we all blew that one! "

    Fortunately we had Tabasco to pull us out of the fire!

    Don't feel bad Bama, I was a little rusty on this one, I just knew they were different than 57 up.

    Mine were hooked up just the opposite so that they looked nice and parallel. Why would it matter Tabasco?

    I doubt the heated air coming thru the heater cares which way the hot water is flowing thru the heater core..

    Because the water pump pushes water and it returns to the radiator through the intake manifold. The water has an easier path through the heater core if it is pushed through the top and flows down through the core to be returned to the water returning to the radiator through the intake manifold.
