need some ideas on a tripower linkage. mine is primitve, all open at once type, that is ugly looking. It has holley 2300 series carbs. Will try to post picture. TJR

T you can get many a linkages of the internet from jegs or summit. there is also a place called hotrodcarbs.com the best ones are made by lokar. just make sure it is a progressive linkage!!!

Have OEM manifold, mismatched 2300 series carbs and no air cleaner. Tri power FE air cleaner is not very close. Made bottom out of sheet aluminum, top of FE can be redrilled to work. Really need some aluminum valve covers.

Just measure distance its off by, bend two carb air cleaner studs each 1/2 that amount. Saw that trick in Ford Performance book, where FE tri power air cleaner lid was used on FE dual quad setup.

You could use to buy a blanc bottom plate. Follow the suggestion of fabricating offset carb. studs as you don't want to modify a piece that may be worth money.
Have you located FE linkage yet? I would imagine that you will have to make some modifications due to carb spacing.
While I have you here, does it appear with the increased carb spacing on the OEM manifold, that possibly cathedral style (center pivot) fuel bowels can be fitted?

Don't know about center pivot float bowls. My gut impression is that you can put them in 2300 holley carbs, but I will check on that. Interesting question. TJR

I bought the 1958 mercury intake (bare) 15 years ago for a 430 powered car. I went to find holley 2 bbls non performance style carbs (maybee 280 cfm+/-. find some standard issue for early 60s ford products holley carb X 3.I paid 10 apiece for them but you must use the 1957-59 style float bowl assy with the metering block (hint these style dont have the external float adjustment on them,you make the adj buy bending on the hanger inside. and trimming the underside of the airhorn everything looks like original. if you use the latter style float bowl you will have to d shape the airhorn like the fe 390-406 setup used. mechanical linkage can be fabricated( I used a anssen kit for the mopar six-pack and some hard work. I then used a single 4 oval ford style cleaner and took the base to the machine shop with the pattern and 2 days had it together.I tried to used vacuum secondaries from holley 4 bbls but too many problems arose.The car is gone but still have the setup on the shelf.I think they are a very rare item. another thing I tried was the autolite/ford 2100 style (you can find these that flow up to 420 cfm) but most are about 300. ford actually has a technical bulletin that shows part #s and assy. procedures.

Be aware that 2V carbs do not flow as much as they are rated

You may find a chart that shows 420 CFM for a 2V but it is critical to understand that a 2V that flows 420 CFM is flowing less than a 4V that flows 420 CFM! The manufacturers set standards decades ago that allow for 2V carbs to be rated at different vacuum levels than 4V's. Many modern 2V's may be rated just like a 4V but old Holleys and Autolites do not flow as high as they are rated and usually only flow about 1/2-2/3 of their rating. Those 900 CFM tripower packages rarely actually flow 600 CFM! Hawkrod

One misconception of the FE tri-power is it is over carbureted for 390 and smaller displacement FE's. One must realize 2v and 4v carbs are flowed differently. 2v carbs are flow tested at a pressure of 3" and 4v carbs are flow tested at 1.5". To make an accurate comparison of 2v VS 4v carb take the total cfm of the 2v and divide by 1.414. Example: Total cfm rating of most FE tri-power carbs (List #2436/2437) is 1030 cfm. 330 cfm primary + 350 cfm each outboard = 1030 cfm divided by 1.414 = 728 cfm.
1030/1.414 = 728
As one can see if comparing the tri-power system to a single 4v intake system the tri-power is equal to a single 4v intake with approximately a CJ carb that is 730 cfm. Ford did the homework, and rather well at that!
