What carb is this its two barrel i thought that 350's in 82' had Quadrajet

Out of curiosity, did GM have a two-barrel version of the electronic Quadrajet?

They did, both dual jet 210 and varajet versions. The 210 was used on the 3.8 Buick and Chevy V6 as well as the Pontiac 301. I have also seen a feedback bersion of the Dualjet 200 where it was a full Q-Jet with the secondaries cast shut. Was on an 85 307 Riviera.

I had only seen the third one. Three of those in a row might be cool on a small engine like a 283!

I prefer three Holleys on a 400 small-block. 350 cfm center carb, 500 cfm end carbs (2-barrel ratings. Rated as a 4-barrel, it's about 930 cfm, vacuum secondaries.)

Photo from trial-assembly about thirty years ago. There have been some alterations...

Yes, that's a full-size, coil-in-cap HEI behind the rear carb.

I think I'd rather run three TBIs than three two-barrel Quadrajets, but honestly, I wouldn't spend money on either setup.

Looks great! Reminds me of 435 hp 427 or 340 6 pack. Its a shame a single 4bbl will outperform it everywhere.

I did pretty good on my 440 Tri-Power Holleys on an Edelbrock manifold

Actually the 3 Holleys beat a performer RPM at every data point. Summit had that setup and Holley still does. Now a single 4 barrel beats the Edelbrock dual quads all day long!

I am glad to see members here know thier stuff!

Those 2GC two barrel cars are the most common stuff from the 1970's - iirc they can rival our TBI's for CFM ratings... seriously.

As to the Dual jet, the first version (a Quadrajet with the secondary side unfinished/closed off) was only done for a couple years, and if you pop off the airhorn of the second kind, or better yet compare the fuel bowl and throttle body portions, you will see that they are still based on the quadrajet design - except unlike hte innagural dual jet, the casting portions for the secondary side have been removed.
