water pump pulley

[Guest]

I'm finishing up a 289 installation and am ready to put on the water pump pulley. However, I find I have three different water pump pulleys lying around, all of different diameters. Anyone know the correct size for a 289 with alternator? thanks-

I have a '64 V-8 water pump pulley off the car, with a 7 3/8" outside Dia. It had an alternator but it is not an exact science measuring with a tape measure and finding the center, but it has to be pretty close.
