Haz,
Some of the pumps have their intake on the right hand side and others on the left hand side. Just make sure that your radiator has its bottom outlet on the side of your pumps intake or you will have to fabricate a hose-steel tube connection to bring it back across. I believe it was Roscoe that spent a lot of time trying to find out why he had a heating problem and finally found he had the wrong pump on his engine. I don't remember if he has the 351 Cleveland or Windsor, but the factory had mis-numbered his pump and he had the one for the other engine all that time.
