    I'm slowly putting gathering parts and such for a 3x2 setup and am wondering if there is any reading material on the setup and adjusting of 3 carb systems? Any recommendations?

    It would help if you would let us know what carburetors you are using.

    Google tripower 2G.

    The problem is that you will find 10 sites with 10 different setup recommendations.
     
  6. Factory style with factory parts is as easy as it gets.
    Venture off that path and you better know because if you ask 3 people you'll get 9 answers
     
  7. ^^^^^ TRUE DAT!

    I know right, I was hoping there was a book of sorts that might help.

    Hello,
    Here is answer number 9...not in a factory tri-power book or a dvd. The vacuum hoses need small hose clamps. They will eventually come off with pressure, if you step on it a lot, like in racing. When that happens, it is not a serious thing, but you won't have max power. Mechanical linkage is fine, but you use a lot of the outside carbs and use up gas. But at .25 cents per gallon in 1958, gas was not a problem. It was just bothersome and if you did not like to lose or be without max power when you needed it the most. The center carb works, the outside two do not...

  11. I am running an Edelbrock C355 with 3- 2G's from 283s. Back when all this stuff was plentiful I bought 3-2Gs from 1968 Buick Skylark with 350 and 2 speed. This combo had #49 Jets. not available from GM. My setup idles on all 6 barrels, spark plugs run sandy brown. I built a staggered linkage such that the 2 outer carbs do NOT begin to open until end of Accelerator pump stroke on center carb. All 3 carbs hit W.O.T. at same time. Measuring the throttle bores and doing the math this runs about 740 cfm. Somebody will complain that is NOT how to calculate 2 barrel cfm.
    After being influenced by Armchair Crew Chiefs I pulled this setup off my bracket car and replaced it with Edelbrock Torker and Holley 3310 780 and ran same E.T. & mph. I guess I had it running correct. It is now on my T Bucket and delivers 25 mpg. I would recommend get 1 carb with Choke House mounted high , on choke shaft, for the center carb and run choke. By the way, a 3 deuce setup at W.O.T. will add 6 inches to your manhood.
