Engine Pulleys Dont line UP
Ive been putting a small block together and I am down to putting the waterpump and pulleys on. Ive got a Corvette water pump on and the corvette pulleys on but the crank pulley is further back (closer to the engine) and the waterpump pulley is to far away from the engine. The belts dont line up. Both pulleys are 3 groove. Anybody got and ideas on what the issue is? Thanks

That would be my suspicion too. Ill check it out I dont have the old pump to compare
. But these are the original pulleys. The water pump is all the way back against the timing cover. I will go make sure that the pump is the right one. Any other ideas if that is correct?

Might not be the route you want to go, but I had an alumninum spacer made to fit between the balancer and the pulley so the belts would line up on my "custom" project. Works perfect. If your interested I'll give you the forum member's name who can machine it for you.

adjust hub
I have had the same problem with my '69. After ruining water pump bearings on two brand new water pumps, I realized that misalignment makes a difference. If the water pump pulleys are too close to the engine, use the Summit spacers. If the hub is farther away from the engine than is the crank pulley, I think the water pump hub can be pressed farther onto the pump shaft the appropriate amount so that the crank and water pump pulleys are aligned.
