318 crank pulley correct size??

my current setup is a single groove alternator and water pump pulley. Motor is at machine shop, so I can't even mock up.
Do the water pump pulleys come with different depths?

The one that I posted is supposed to be the correct one for non-A/C applications... That's what worked on ours...

A/C uses a double belt and double pulleys to drive it...

Non A/C only uses single pulley and belt...

If you use the proper combination, it will line up correctly with the aluminum water pump...

Cast iron water pump takes different pulleys...
