Default What carb do I have?

Hey everyone, i picked up my 1976 last year and have very slowly been working to get it back running. In reviewing all the things I got along with the car I see that I have two carbs. One is installed and the other was in a box. Any insite to what I have would be helpful!

The Corvette Black Book lists carburetors. For 76, the 17056206 was for base engine cars with AT. 17056226 is listed for the L-82 with AT and factory air. Your 9226 is not listed for Corvettes.

That's not correct.
  • Carb number 17056206 is a 1976 Corvette and Nova carb, Federal emissions, with auto trans. This is an 800 cfm carb, and is a great Vette carb.
  • Carb number 17059226 is a 1979 Chevy and GMC truck carb for a 400 with air and auto trans.

Hey Lars,
I was hoping you’d chim in on this one! So the correct carb is currently not installed on my car. Is there anything I should check before swapping them out so I have the correct one on there?

Yes - you need to completely rebuild, repair and set up the old carb before attempting to just bolt it on and run it. It was removed for a reason. That reason is usually that somebody forked it up.
