Generally, the pulleys aren't balanced as part of the rotating assembly.  I've had several engines balanced over the years, and never did the shop allow me to include the pulleys.. Smiley   .   They balance the internals, and then balance the damper and flywheel.

Here are a couple of photos I took. Maybe not the greatest but at least the parting line on the top between the two fan belt grooves is pretty apparent. These are two pics from two pulleys I have and not two shots of the same pulley.

So do I have only the 'front' pulley, Jon? Can you take a pix also of the front and the back?

Gary, to me it seems like you only have the back part of the pulley (the rear groove).

Yes, that's the way it appears, given the stamped number on the front...   I've also got a couple of questions concerning the difference in damper between the '67 and '69 302, but I'll start a new thread for that.   Since you have a '67 Z28, Jon..  I Hope you can help me out again!  Smiley
