2GC carbs

I'm building a tri power set up. I picked up 3 2GC carbs. Small base with side inlets. I plan to rebuild them. I can't figure out what rebuild kits to get. The kits are listed by year of vehicle. What years were these carbs used on?

 

These are what I ordered for mine.

Small base, side inlet.
Does one of them happen to have one of these number tags on them?

The kit comes with so many different style gaskets, you should be fine.

 

I've got 3 kits sitting in the shop to rebuild mine, I got them from NAPA. I'll look at the part numbers tonight when I am there and post them for you.

The number I used is 96-111D from GP Sorensen. I get them from my local Auto Zone. they stock them. I have no idea why. Keith

 

Pontiac used them from '57 to '66 on the fullsize and GTO's. I believe they were also used on Vettes in the early 60's but not sure on that. I'm a Pontiac guy not a plastic rat guy.

 

this subject is WELL covered on the HAMB try your luck with the search feature . I'm going to geuss, what you realy need to do is buy one of the 3 deuce adapter kits available. just putting 2G carb kits in them does not make a 3 deuce set up..... the pontiac set up is different.. and chevy didnt do the 3-2 thing

stand corrected

 

Chevy did do the 3-2 thing. From 58-61.

 

Check out Vintagespeed.com in Vero Beach FL. Charlie has a great kit with everthing you need to make a real tri-power set up. I have used his complete kits with great results.

 

Chevy did the tri power deal from 58 to 61 on the 348 engine. Chevy used the small base carbs. Pontiac also did a tri power, don't remember years, they used small and large base carbs and a combination of both. Olds had it on the J2 which was around 1957. End carbs were dumpers, base plates are being reproduced there is no provision for idle adjustment screws. Either their off or W.F.O..

 

66 chevy pickup with 283 had side inlets.

 

63 Pontiac Tempest 326....Rochester 2CG 65 Biscayne 283, 2bbl. I owned both of those cars and they both had 2CG's. Small base,if I recall correctly.

 

I looked at the kits I bought for mine and they are NAPA 2-5146C. I think that is a generic kit that fits most of the 2GC carbs.

As said before, you cna everything you need here. They have the full kits with all the items you need to rebuild them and to turn 2 of the GCs into end carbs.

my home built 3-2s using the specific parts supplied by Charlie @ Vintage Speed like Longer throttle shafts and thicker throttle plates and other special parts to convert the end carbs to dumpers. If you can get past his wife he is very helpful if you have the experience to do them yourself. The carb kits I got from Ebay I think. It's more involved than just new gaskets in an old 2 bbl carb but it's not rocket science either. It was great fun for me and I can say that I did it myself.



Notice the different thickness of the the throttle plates on the left supplied by Vintage speed with the original plates on the right. They have the throttle bases with the thicker plates and longer shafts already installed but I have more time than money and besides it's fun.



I was able to find a truck carb that hooked up to the original Ford 6 cyl choke cable already installed in the dash.

 

I'm in the middle of rebuilding my 3x2 setup and i found this pretty helpful

EXCELLENT! Thanks x 3!!!!!!!!!!!!!!!!!!!!!!!

 

I probably wasn't very clear. I'm not rebuilding a tri power but building one from scratch. I'm using an edlebrock intake. Swap meet 2GC carbs and a tri power kit with new bases and linkage. I still need rebuild kits to get gaskets, ac pump, floot needle etc. With the information you guys have provided I was able to find the correct kits. I'm building the same combo as shown on Stacey Davids viedo. Thanks for the help.

 

I got my bases from flea-bay from this guy. http://www.ebay.com/itm/2-CUSTOM-TR...Parts_Accessories&hash=item46035b6674&vxp=mtr

Picked up one of these http://www.speedwaymotors.com/Rochester-2G-Extended-Primary-Carb-Shaft,22248.html

Three of these http://www.autozone.com/autozone/pa...1BE969E5E25.diyprod3-b2c5?itemIdentifier=3446

And a Edelbrok intake, (I know could not fit an original one) then a bunch of cores.

I turned a manifold on my lathe screwed some inverted flare fittings into it. Bent up some hard line.
Now I knew how much room I had left for the linkage. It took me awhile to figure out the geometry (math not my strong suit) I turned some threads onto some 1/4" steel rod. Yes it is a progressive set-up. If anybody wants, let me know and I'll post up some pics. Keith

 

Sounds good, Keith!
I'd love to see some pictures...

 

Here is a side shot. One of the linkage arms is missing.

Here is a close up of the fuel manifold. I should have used regular steel lines for the hard lines. However I had this in the shop. I'll swap it out after it goes on the engine. Manifold needs polished. I bored it clean thru, psi gauge at one end, inlet at the other.

 

Next up is the Forward carb linkage. Its i straight thru bolt and nut to the throttle shaft. The washers again are temporary, I will turn a proper length spacer when installed.

 

Here is the missing control arm. This is not the finished product, hence why it is so clunky. A simple set screw secures it to the extended throttle shaft. Another turned part (not shown) connects the primary rod to the primary control arm. It slides back and contacts the stop collar on the arm at about 55% of travel. This is shown in the closed position.

 

Here it is again at WOT. I cant find the connecting part, I need to be better organized.

 

The '66 GTO had 3 2GCs. Prior to that year Pontiac ran a smaller center carb with the 2 GCs as outboard carbs. I had a 66 GTO with this factory set up, progressive linkage and it was very very fast and dependable. Now I'm running a '68 427 with 3 holleys in my 55 and don't like it nearly as much. Still damn fun though.

 

Mr Nick, I have built a number of these units, as has already been identified 3 x 2GC Rochesters don't equal Tri Carb set up! It is important to establish a primary , centre carb & secondary , outter carbs set up. The primary carb supports the vacuum & idle circuits for clean idle and crisp transition into the power& cruise circuits of all 3 carbs. Secondary carbs a phased a little later than the primary so as to get some air speed into the primary before the noise really starts! Hope this info& all of the additional posts help you get going in the right direction!
