What is this crank pulley from?

[1969cuda]

Iv’e had this in a pile of parts for quite some time. So long that I can’t remember why I was saving it. Anyone have any idea?

318/340/360 w/PS 72
318 only w/PS 73/74 (maybe later, didn't check)

My guess is a engine. But I could be wrong.

I have... THey use different diameters to for making the pulley and belt move faster or slower...

Just look at a 67 - 69 small block crank pulley with p/s and a/c... They have different diameter grooves for the various belts...

I’m saying 70+ small block p/s non AC
I would guess the pulley works on any engine. I just bought one Friday
