This needs a bump and should be in the How-to section for reference...
Interesting, I have one that looks strikingly like that one. I found mine on a 1962 413Here is a rather unusual cast iron small block pulley.
It was found on a 1970 small block & had been added on in front of the stock crankshaft pulley.
It is part of an 'add on' Air Conditioning kit. The name ' RIGIKING ' is cast into it along with the number 9117618 while the paint applied number is 91-17619 ;

Been doing this for years with fluid dampers for alignment. I still have it on to run just the alternator. But I shut the GM single wire alternator off with a solenoid.Well, I just remembered that both of my 273's (factory A/C~P/S cars) had small diameter water pump pulleys. I think that's related to the fact that they WERE factory A/C~P/S optioned cars, and this is back on the cast iron water pump cars. I don't have one of these pulleys in my stash right now, but maybe if someone else does, they can post a pic with dimensions.
Also, if you think about it, that smaller diameter water pump pulley will spin faster......probably for a logical reason.
There is a wanted thread for this pulley. KimSmall block Crank pulley Single groove.
