It was on my 383 when I got it and there are no numbers on it. I’m switching to a small block and I just tried this one out for size and it’s working with my hillbilly setup that I’m trying to get working!!!

I know @oldkimmer had some pulleys and so did @RAT ROD AL ... not sure if they can be of any help with your search.
