The Cast iron pulley application. 3923898 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a couple of these pulleys and was wondering exactly is the application. Best guess it a BBC C10 Truck. Anyone help me out? I think I got the casting number correct?

In my experience with those it is a small block add on crank pulley. It is normally accompanied with the same power steering pump pulley as a big block if that makes any sense.
