Are you sure that's an '82? Haynes lists 4bbls only in '82,'81 was the last year for the Rochester 2bbl.

I'm Awesome
Our 1980 C10 350 2bbl had a Rochester Dual Jet (front half of a Q-jet) not the older 2GC.
My '79 had a factory Dualjet. '74 had a 2GC, though.

That's a Rochester 2GC, the old style 2 barrel. The Dual Jet that's been mentioned, is the front half of a QJet, and is what was used in the mid 80s before the switch to TBI in '87. Our '81 Sierra pickup with a 305 had a Dual Jet on it. That was actually a reasonably fast pickup!
At least three different styles of DualJet. One based on the primaries of a Pre-75 Q-Jet, one based on the primaries of the '75-newer "Mod-Quad" Q-Jet, and one with a smaller body.
All photos taken at my second-favorite Treasure Yard, 'cause I sure wasn't going to buy these things.

Note that the primaries of a Q-Jet--or the throttles of a DualJet--are smaller than those of a 2GC. Lower CFM, lower performance--but within their capabilities, they're a wonderful 2-barrel; in particular the 200 and 210, having most of the improvements of the '75 Mod Quads. If memory serves, the 200 and 210 also have the larger venturies of the "800" cfm Q-Jets rather than the venturis of the "750" cfm Q-Jets as in the DualJet 165.
Out of curiosity, did GM have a two-barrel version of the electronic Quadrajet?
I should know that.
And yet, I don't. I may have to dig out The Big Book.

Probably did, but the only thing we ever had was the 81 Sierra pickup, with a 305 and the Dual Jet. Dad never had to rebuild it, so I never got that good of a look at it.
