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

E-mail or call the Summit tech department to get dimensions.  I don't think you will find anything that is a direct bolt on, but you might find a 5/8" shaft pulley that can be opened to 3/4, and spaced out to line up with your damper.

Autospecialties can make a pulley for you if you specify dimensions.

The bolt pattern is pretty common.  Your main concerns will be the offset, and groove spacing.

Howdy Charlie,

Yeah.  I noticed that most water pump pulleys (Y-block too)  have a 1.75" bolt circle.  Seems to be pretty "standard"

It also appears that there might be a "standard" offset for "short" shaft pumps (and long shaft too) 

Mine appears to be 2 1/4" offset.




Ahh well, Summit tech "support" was NOT very supportive on dimensions.

You can also contact the manufacturer directly, March, Billet specialties, etc.

Yes, The Summit guy did suggest contacting March!


I'm getting closer!
