I'm wanting to know if there is multiple Waterpump pulleys for the 6" long Waterpump? I've got a 5 5/8" , wanting to see if there's a larger diameter pulley, thanks in advance

 

There's a number of pulleys made from 1964 to the 1980's that will bolt up but they may not line up. They may only be off by half a groove width, but that may be enough to throw belts or wear them out really fast. It's best if you can get a matched set, or tell us what the code is on your crank pulley so other members can try to match it.

X2 on that. It's best to get a complete matched set. (if you can)

 

I'll measures the depth of my Water pump pulley tonight and get back with you, didn't know there were that many pulleys that fit the long snout pump thanks

 

Okay folks, I've got some measurements of the 3 groove Waterpump pulley, ALL FROM THE FRONT OF THE PULLEY NOT THE BACK MOUNTING FACE- so overall front to rear 3", not using the first pulley groove, from the front of the pulley to the 2nd groove is 2 1/8" the third groove from the front of the pulley is 2 5/8" overall diameter is 5 5/8" I need a larger pulley if y'all can help me with what stamped code or if you have one that matches them measurements, thanks I don't want to remove the pulley till I get another, thanks

 

Alas, Chris Wit had a database of pulleys with ID codes, diameters, applications, etc. Maybe he distributed it like he did the part number database and someone can look up what you need.

 

Thanks fun71, I didn't want to remove the pulley till I had another to swap it with that's why I just measured it
