Could this be the "Yeti" of Pontiac carburetors!  Thanks for your help.  If you ever come up with an answer I'd love to hear it.

I had one here a while back but forgot about it.  It was 10 years ago and I verified the job and part number in Quick Books.  It was sent here by the owner of a Pontiac T/A and was stock on his engine but I can't remember if it was 400 or a 455?  The work order only shows what we did to it, not the engine size or specs.  I'm pretty sure it was a 455 and auto transmission but not sure if he transplanted the 455 into the T/A to replace a 400?.......Cliff

Interesting.  I'm amazed that the part number never made it to any Pontiac/Delco literature.  Thanks again Cliff.

 That was a SR carb for the 1972-1974 Super Duty and Hi-Output FB's. See several references of it in my manual and actually found the an old Echlin kit part number for it.

Cliff Ruggles:
It's not the 73-74 Super Duty replacement, they are part numbers 17054910 and 17054911.  They did make a few SR with part number 7044270 nearly as I can remember.

The 7044276 may have been for the standard 455 engines in 1973-74 if it showed up as a Service Replacement, but the Super Duty engines were completely different and took carbs with very generous idle fuel delivery, and they were the larger "800" cfm castings......Cliff
