Howdy all!

This question probably gets asked frequently, but can anyone tell me what after market  DUAL-GROOVE water pump pulley works with Y-blocks? 

Some water pumps have a 0.625"  (5/8") shaft and others probably mostly truck pumps, (mine) has a 0.750" (3/4") shaft.

I have a dual groove OE damper and I want to use dual V-belts with the A/C pump and 100A Alternator.

Summit Racing has a couple of pulleys that are supposed to be used with 289/302/351 engines.   They don't offer dimensions (offset, pilot shaft dia etc).    I don't want to buy one and have to send it back!

Anyone?


Thanks!

Rick
