crank pulley part number ?

I'm trying to run down a 2 groove, lower crank pulley number allegedly for a B/RB but I can't seem to find it any of my parts books and Google is of no help. The part number is 2513 947

Anyone ?

Your Google Fhu is not very good ...
linky

Ooooookay, let me rephrase.

There is a pulley listed on eBay that is supposedly "from the mid 60's" which carries the part number 2513 947 that I'm interested in purchasing. I would like to verify the application of this pulley, but I can't find it in any of my parts books or Google searches.

That part number shows up in the 1963-68 Truck & 1968-71 Medium Duty Truck Factory Parts Catalogs as an accelerator shaft bracket.

I was thinking it might be a truck application, but not exactly that application.

Thanks for the help.

Marine part number.
I have the very same NOS pulley ,
same written and stamped numbered pulley from a Marina that
had tons of Chrysler Marine parts.

Great info, thanks.

Was this a small block or big block pulley ?

....and if you happen to run across it someday, could you measure the diameter and height for me ?

Thanks much.
