There's a group of folks (myself included) that have been trying to get Holley to reproduce these for years.

Steve,

I know this is an old entry, but I just found it. Got a 239 running great, a 49 engine I think as it says 8BA/8RT 6520. Got a Holley 2bbl (now) but I got an Edelbrock Triple Deuce recently. I want to do what you said in this post, run on one carb (center). What is the proper way to blank (block) off the other two carbs?

Any advice would be helpful.

Thanks,

Joe

 

First be sure the plenum under the center carb feeds all the intake passages, just like the single carb manifold. Next mount the outer carbs by cutting a thin aluminum flashing solid gasket and place between two carb base gaskets (flashing available by the roll in the roofing materials dept of your local DIY store or ask a roofer or aluminum siding guy for a scrap. You can find it with a brown finish if you want the block off to be less obvious). It's critical there is no vacuum leaks. Do not hook up fuel lines to the outer carbs or use dummy lines not connected to the fuel pump. Finally connect throttle linkage to the center carb only. If it is important they look like they all work, us progressive linkage, but modify so it does not open the outer carbs or remove the butterfly disks in the carb throats of the dummy carbs. If you add aircleaners or velocity stacks on top, no one will be the wiser.
Oh, be sure the center carb has a choke and you connect it.

 

Hey EXracer,

Thanks a bunch for the quick reply . I'll do just as you say. I got all the stuff to do it right here. When I'm done I'll report back with the results, and I'll post a few pictures of the process as well. Right now I'm rebuilding the center carb. I might add it to the page I have on my 47 Ford Coupe.

Thanks again,

Joe

 

No problem, glad to help!
By the way I am not a EX racer, but an AX racer. AX is an abreviation for autocross, (a high skill precision driving competition where the competitors drive thru a tight twisty course as fast as possible against the clock. In our racing, races are won or lost by thousandths of a second) where I currently and passionately compete nationally.

 

Before I found FTE, and I was looking for information so I could choose the best intake and carbs, I came across some old threads. There is some great info.

Fuel and Carburetors

 

Thanks HD74,

Good info at those links. Following the instructions from AXracer, who I mistakenly turned into an EX-Racer, (sorry about that ) I'm making headway.

Turns out the Edelbrock is brand new, somebody just painted 3 Ford 8BA carbs after a quick minimal rebuild and set 'em in place. Never checked it out as the linkage was not even adjusted. They even got spray paint in the throats. The images below show the setup I got, what I built per AXracer's instructions, and the underside of the manifold. I also made a map of the airflow to insure the center carb covers all. Let me know if anybody needs it.

I appreciate the help. I'll keep you posted. Oh, got this on eBay for 275, as a "buy now".






This little guy was new


See ya

 

I know only two people that had triple deuces. First guy had 390 FE setup that ended up being stolen. Second guy had 427 vette, commented if it wasn't one damn carburetor it was another. I tune a customers 59 TR3, every year , with dual carbs. Good Luck

 

So what's your point? Triples have been on flathead forever and way before anyone ever heard of a TR3, 390 or a vette.

 

Won't help much with it getting stolen, but I think that the problem with keeping them all working in sync is the reason MM wants to run a single working carb and two dummy carbs. The real solution to keeping multiple carbs working proberly is to invest in a set of the new repops or the updated design ones Barry Grant makes. I think they still make the tool to balance a set of originals, Uni-sync I think they called it.

 

Making great headway on my Triple Deuce project for my 239 ci. I've rebuilt all carbs and am happy with the outcome. But I ran into a little problem that I had to work around, or rather grind off .

In researching it, I could only find one site mentioning the problem. It only applies when putting the vintage Ford model 94 carb (Chandler-Groves / Holley) on the Edelbrock 1108/9 manifold. The front carb and the alternator occupy some of the same space.

I took a little extra time to make a webpage to help anyone who might be having the same problem. Here's the link.

Holley 94 / Edelbrock 1109 overlap

I called Edelbrock and they were totally unaware, but concerned, since they just recently released the new Edelbrock 94, a replica of the vintage 94 carb. In looking at their image, I suspect the new carb will have the same problem, only now it's within their own product line and not just a vintage 94 compatibility problem.

Here's an image of what I've got so far.



I'll let you know when I'm done.

 

Nice looking setup!

Usually folks offset the generator or alternator to the side when running 3-deuces. With a generator, there's just no question it has to be done.

Quoting from the Speedway catalog for this setup:
"So, you've got your Flathead topped with a row of Strombergs on an Offy intake, but now you have no room for an alternator! This bracket kit can help solve that problem by mounting the alternator on the driver's side of the engine. "

I came onto a relatively rare early '50's Offie triple-deuce manifold made specifically for racing. It didn't even have the generator mounting bracket on the front of the manifold, because they assumed you would mount the generator off to the side.

 

Those 94's are looking super sweet! Great job. Just as Ross has mentioned the Alt or Gen will have to be offset. There are a lot of different offset bracket out their from Offenhauser, H&H and Vintage Speed to name a few.

 

Hey ALBUQ F-1, thanks for the great info and the image. If it's okay with you, I'd like to add that image (credit given) to the page. I had no idea a bracket was available. I might even try it if I experience any problems with the mod I've done. We'll see.

I used to live in Albuquerque from 71 thru 76, great town for old cars, lots of good junkyards. I miss the Digital plant and the people I worked with.

Thanks again for providing that info.

 

I wouldn't use that Speedway set myself on a pretty engine, others make an aluminum bracket that fits in the original intake slot and move the alt over about 4 inches. Here's a pic of what the Speedway setup looks like installed, and the other kind (for a gen, but similar). NOTE: you may run into the problem others are having with wide belts/truck pumps and alternator brackets!!

LOL, the Digital plant was declared a toxic waste site, now it's a mall! The Philips plant is used for movie making.
