It pays to know what motor you really have!

['65 chevy lover]

I posted several months ago about the water pump pulley for my 283 not lining up correctly. I posted on this site about the problem and everyone including myself was wondering WTF! I had to change the location of the pulley mounting flange by removing the back of the pump and supporting the shaft and pressing the flange down 3/16". As it turns out, the motor was really a 305. I checked with O'Reilly and sure enough, different part numbers. That explains what the deal was. It pays to really know what you have. I kinda feel like a dumba$$...oh well, chit happens...LOL
