I may be wrong. This thread indicates that only Mercury '58 tripowers had vacuum secondaries, and all of the FE tripowers were mechanical.

So, anyone have experience with a tripower on a y-block with a fordomatic?

I havent really seen anyone run a 3x2 with a fordo. This is what I'm trying to find out since this is what I will run on my car

I've considered a tripower as well. I'm worried that with a fordomatic, the engine will bog horribly when I floor the throttle... at least until the transmission downshifts.

Mercurys, Oldses, Vettes, Pontiacs and MOPARs all had tripowers (or "6 packs") with vacuum secondaries, at least at some point in time.

Then again if the FE birds (all automatics, AFIK) with tripowers had mechanical linkages, perhaps it's not so bad...

Thats the thing.....If those big blocks had tri powers and autos that didnt bog im sure it will be fine. Just need to be adjusted correctly

If you are using the 2 barrels like the 94's (ECG and EBU style) from the mid-fifties then I would think to get "vacuum secondaries" (meaning that the two end carbs only come in when engine vacuum demands it) you are going to have to rig up some type of a wild triple carb linkage setup that I have never laid eyes on. I am positive that the 58 Merc would have used those 2300 style 2 barrel carbs... A MUCH DIFFERENT ANIMAL than the mid-fifties 3 bolt flange carbs, so I have no idea if that linkage assembly would work.

I have seen plenty of 3 deuce setups on a 55 or 56 that run an original Fordomatic transmission. However, the ones I have seen use the 2 barrel bellcrank that attaches to the two hole bosses that are almost directly in line with the carb as you look at it from the center. The bellcrank in your original photo is one that is used "offset" of the carburetor and to the driver's side. The teapot carbs and almost all 4 barrels are actuated this way.

EDIT:

Take a look at the following photo of Speedway's 3 deuce linkage. If you run 94's this is what you need...



It can be hooked up as progressive or all out with the butterfly shafts. They actually took this photo with the center pivot down instead of up like it is supposed to be so the pivot holes would just about line up all the way through three carbs.

So you are saying if I find an original 2bbla bellcrank it should work just fine?

Yeah it definitely has to be progressive linkage. I found the whole set up like I said but its from a v8 4bbl fordo car. I would like to know what all from the linkages are the same from the 4 and 2 barrel carbs?

I havn't set up a 3 deuce for a long time but can't you use the stock bellcrank with a rod to the center carb? If the carb linkage setup is on the passenger side wouldn't the stock 2bbl unit work? Chuck

Chuck, you are correct. Problem is the OP want to use the Four barrel bell crank. Don't think it will work since the rod is on the drivers side of the carb. Already mentioned that a few post back.

I have extended throttle shafts on my 97's so everything mounted on the drivers side. You might be able to use the four barrel bell crank if you do that. I can't say for sure. I use a Lokar Cable. Also use a Lokar Cable on the kickdown for my C-4.

Well I wouldn't mind using the 2bbl set uo if I can find one. Any leads?
