I already have one of the short-shaft water pumps from Jim Carter. He says that he's sold 500 of them with the 4" pulley with no complaints.

But since 7" pulleys are more expensive than 4" pulleys, I've got to think that GM put the 7 inchers on for good reason.

Fred T, The top of my radiator frame has already been cut (which helped in pulling the engine/tranny). That's a real option.

The $73 for the short-shaft pump plus the $20 core charge which I'll probably have to eat (no 261 pump to return) plus more fussing with a pulley just has me thinking of other solutions.

Thanks, everyone!!
