Pulleys for a 390 Cadillac engine???

Anybody know what pulleys to use if you want to have single grove pulleys and not the stock multi groove pulleys? Does the chevy single groove pulleys work? Any suggestions?

 

Bttt

 

Boy i dont know.... I have some stock ones

 

I think the early 331 motors have a single groove pulley, but dont quote me on that. Seems like you'd just have to find a car without power steering, if there was such a thing...

 

I have some AC car pullies, looks like they have the extra pulley groove just press fit into the standard pulley. Maybe could seperate the two to get a single groove pully?

 

You think I would be able to machine a couple of grooves off?

 

You are exactly right, I have a '51 331 single groove pulley sitting on the shelf...no power anything...
