Can anyone tell me the Diameter of the 1967 330 crank and water pump pulleys?
Hoping to use the short pump (5.1”) which I’m told is correct for that engine.
Bought a set with the engine but crank is 6 1/4” and WP is 7 5/16” and too big!
any info appreciated.
anyone have a set of pulleys for short pump for sale??

 

With or without PS and/or A/C? Yes, 5.1" is the correct water pump.

Here are the factory pulley charts for a 1967 330.
