Hello.Let me be the first to say welcome.

It sounds like you have the wrong water pump.Ford made like a dozen different water pumps for various 289/302 applications,all of which would bolt right up to the timing chain cover.The main difference was how far the impellor shaft stuck out,which is what determines how the belts line up.If it was my car,I wouldn't worry about it if it's just off by a little bit.If it is off by half the width of the belt or more,I'd have to start trying to hunt down the correct water pump.Hope that helps.
