Default Rochester Quadrajet Question

My 71 BB came with a questionable carb. I know this forum has some very intelligent members so I need your help once again. What follows is a list all the numbers that I could find on the unit. If anyone can nail down the year and application, I would be eternally grateful. Here goes: 17085212, 1765HPA, 80576R, 17073362, butterfly#29909
Thanks to all,
FEVER

All my books are in a box right now but....a '1' as the first digit of the part number means its a later model carb....late 70's.

I don't see a 17085212 listed for any year corvette. Hopefully someone will have the correct application.

Thanks to all for your help. My suspicions were well founded. I knew it never had a chance at being original. Anyone want to buy a truck carb??
