My pulley is a triple (hard to tell in the picture). I think it would work for you if you cant find a double.

Hi Mike... If you could measure the depth sitting on a flat surface. Need that figure to know if the pulleys will line up. I'm thinking it may be for an AC car??
Thx

The pulley came off a Mark IV 454 that was in a 67 Impala I bought years ago. It didnt have AC but the engine may have come out of a car that did, I dont know. I replaced the steel pulleys with Billet Services aluminium pulleys when I dressed the engine for my Nova. Everything lined up perfectly.
I took more pictures that I hope will give you the info you need. I think it is the same as this unit from Summit which, according to its application, is what you are looking for.
Hi...I'm looking for the crank pulley. It does not have ANY GM parts # stamped on it. All I have is a description...
Double pulley, engine is 454
6 3/4" across, 3" deep ( laying on flat surface to top of pulley)
Long water pump, ( not sure of the year of engine, it was a transplant, I think it's early 80-84 CE replacement block by the engine stamping)
I don't have a parts book this new...
THX in advance
Summit racing has about 150 choices,

I think this one is from my 454. Look right?
Ill have to pull it out and measure it.
