I second what Fevre said. It is a short style but with a larger diameter shaft. I got mine from NAPA. I didn't feel like spending $130 for an aluminum pump. Wow, it's cooling question day. You're the second person to ask about water pumps today.
....edelbrock also make a Corvette (68---82) style victor series aluminum water pump, not cheap, but if you want to keep your vette cool...it real nice lookin to

The small block Chevrolet engine used one of 3 water pumps over the years. They are referred to as short, Corvette, and long. The short and long pumps used a 5/8th inch diameter pilot shaft at the fan attachment. The Corvette pump used a ¾ inch diameter pilot shaft to mate to the fan. Measuring from the mating surface to the block to the point where the fan attaches the pumps measure;
Short – 5 5/8ths
Corvette – 5 13/16ths
Long – 6 15/16ths
The GM part number for an aluminum high volume Corvette pump is part number 14011012. They are still available from GM.
