I presently have a rebuilt 292 w/312 heads in my 56 Customline running a 3 deuce setup (Holly 94s). The center carb only is being used (front and rear carbs blocked off). I plan on hooking up all three with progressive linkage. My problem is that I have 3 Holley 2110's and would like to use these to replace the 94s. Advantage? Disadvantage? I am going for more performance, but with economy when just cruising. I'm replacing the factory 3-speed standard with a rebuilt AOD. I've already replaced the stock rear end with a 3.10 9" rear from a 57. Are these 2110s better than the 94s?

Doesn't anyone know the answer to his question? I'm a little curious myself.

I don't have the answers but am going through the same thoughts about my 3x2 arrangement. First off, 1 carb can be a real pain, three can extend the frustration by that much. If I was going for performance and reliability, a 4bbl would be my choice. I'm not a 94 expert at all and just applying my more modern knowledge of carbs to them. I believe that the CFM of a carb is basically determined by it's venturi size. In my case I have 1 1/16" 94's and have read that 94's flow up to 190 or so CFM. Three of these add up to near 600 CFM which, in theory, is more than enough for a 312 CI engine. The 2110's were probably the last go round for the 94 style carb before the venerable Ford 2 barrel that began in 57 I think. The 2110's have "automatic" exhaust heated choke caps and dash pots (anti-stall diaphragms) for increased driveability. I intend, at least at this point, to use a 2110 for my primary carb. Old school folks don't like the "clutter" of these things for visual reasons and I understand the reason. I'm not up for that. I don't want to see another choke cable and handle ever again. I will replace the exhaust heated choke cap with an electric unit wired to the alt/gen so the choke is heated when the car starts and clean up the ports on the carb for the old heat tubes. With some creativity and craftsmanship I think it would be easy enough to make a good looking installation. The dashpot will stay as I hate stalling the car on a sudden stop or short burst of acceleration at crosswalk or parking lot which requires stopping when something gets in the way; pedestrian or a "who is going first" dance at a 4 way stop sign.
As for the secondaries I expect to use the traditional 1 1/6" ECG-6's with progressive linkage. Thanks for bringing this subject up as I hope there are lots of opinions on this and looking forward from some old schoolers who know a lot more than I about these carbs.

I've got a box full of 3 bolt Holley carbs. Some are marked 94, some 2100 (manual choke) & ECG5 on one. The main difference I see between them is the 2100 & ECG5 have venturi tubes that are longer than the 94's. They also have spark valves. I think the longer venturi tubes on the 2100, 2110, ECG5 & ECG6 are why they flow better. The rule of thumb I use on a 3x2 set-up is run your biggest carb in the center & whatever else you want on the ends as long as they match. The biggest pain is getting the right power valve and jet combination in the center carb. The end carbs you can block off the power valves, disconnect the accelerator pump if you like and run the jets close to what the center carb is. They can be a pain but you can't beat the eye-candy factor. I'm such a glutton for punishment on these that I'm working on a 6x2 set-up for mine. Hope to get it going by summer if the money holds out.

Looked through Ebay this morning and it seems the Y block tripower set ups are coming out of the woodwork. I think I saw four including one that actually crammed 3 scrub Rochesters together on a Edelbrock. BTW, the Sanderson headers for my Tbird were delivered yesterday. Going to be awhile before I can pull the motor though. I need to repair a trans leak. We are in the midst of a home remodel and I have the garage packed with 3 cars including the Bird plus lots of stuff from inside the house. I hope this gets finished soon.

I noticed that too Mark. If Edelbrock start reproducing the tri-power manifold maybe the price of used ones will come down.

I'm not a carb guy by any means, and I have 1/16" bore Holley 2100's front to back on my Bird. The primary difference in flow among the 94 family is due to the bore size. "94" is indicative of the 15/16" bore size (.9375") on the first 94's. They continued to be called 94's even when the 2100's (Holley) and the ECG (Ford) updated carbs came out. You'll find that there are 15/16", 1" and 1 1/16" bore sizes. Before you spend the money on getting your coarbs going, read Ted's thread on the 3x2 manifold comparison. i suspect you'll want to swap out your Offy intake (at least that looks like an Offy) before anything else if performance is what your after.

I talked to the Edelbrock reps at the March Meet at Famoso Raceway last weekend. No new 94 on display. If there was a place to display a new product like that it would be the March Meet. The reps weren't to enthusiastic about the carb other than to say maybe around 350 to 390 bucks for one. It appears they have dropped the secondary version already in the catalog so you would need to buy three primaries and convert two to secondaries. Not cost effective. As far as the manifold, they were more cryptic saying it would be late summer before it would be available. I'm not holding my breath on any of it. Seems to me they are "floating" the idea of making one to see what the response is. Even if they make a new intake the purist part of the market will still put a mint original over a repop. My 2cts.

I'm with Mark. Remember Jr. isn't a big fan of Y-Blocks (unless he figures he can make some $$$).

.......My problem is that I have 3 Holley 2110's and would like to use these to replace the 94s. Advantage? Disadvantage? I am going for more performance, but with economy when just cruising.An advantage of the Holley 94’s over the Stromberg 97’s would be the capability of using the vacuum advance on the '57 and up distributors. The center Holley 97 would require some simple modifications to the ported vacuum circuit though. If simply running a centrifugal advance distributor, then that advantage would not be there but the addition of the vacuum advance during cruise situations does add some additional fuel economy to the equation. The Strombergs themselves can be fitted with vacuum advance capability but simply takes much more work.
