I need the stock specs for a 17050213.
Kenth:
This is what i have on the 1980 350 HD Truck 17080213 Rochester and Carter units.

That's very very helpful, thank you Kenth. So it appears that the base plate has been switched, but with this information I should be able to set it up correctly. I've already drilled the mixture discharge ports to .108, and the bypass air is not hard to change.
Your list explains the differences between what MCX and Novadude have provided and what I've measured. This looks like a combination of both Rochester and Carter. I wonder if it's a high altitude calibration.
My thanks to MCX, Novadude and Kenth for your help with this, it's much appreciated.

Correction: I've already drilled the bypass for .108 set screws, the idle mixture holes I've still got to size to .086.
I was just rereading my post and realized I put in the wrong information.
novadude:
Based on Kenth's info, it looks like the 17082213 and 17080213 are pretty close. What I have listed as POE for my 17080213 are the discharge holes above flaps. For some reason, I did not document the well re-fill holes.

True, I don't know if it would matter if I used either of the specs as long as they're all from the same carb.
