water pump issue

I just purchased a new w/p for my 66 300 I6 and the body of the pump is shorter that the original and my pulley is hitting the timing cover...is there 2 different length w/p or is O'Reilly's made in China POS my problem?

Make sure you didn't get a reverse rotation pump for a newer engine.

I think I stole it for $600, it has power disc brakes and power steering already, offenhauzer intake 600 cfm 4 barrel carb, split exhaust manifold, pertronics electronic ignition and flame thrower coil, the old owner had just put brakes on the rear, it needed cooling system love, I pulled the top tank off the radiator you see in bed, rodded it out, soldered it back together, pressure and flow tested good, just replaced the w/p and now just need a water outlet housing, and a good flush, when i got it home i put a battery in it and it fired right up and sounds good, after i changed the oil filter and oil it idles around 35 psi oil pressure and goes up around 60 at high idle, the old owner said he thought it had a spun rod bearing, if it does it sure don't run like it! he said it had a squeal noise coming from the engine, i found the alt belt loose and a vacuum leak maybe thats what he heard!
