Dual Carb Linkage Question

[Jim Shepard]

I plan to put dual carbs and cast-iron headers on the new engine for my B2B. It occurs to me that I've never seen this setup on one of our trucks - in fact, I think the Offy intake comes with linkage for the cars because it comes across the top of the head. The truck linkage comes around the backside of the block and bolts to the exhaust manifold. Does anyone have a photo of one of these setups on a truck application? If the linkage that comes with the Offy is for the car side, how does one make it work on a truck?

Just taking a guess here as not that familiar with trucks If there is no way to make the truck linkage work maybe you could use linkage from a car.

Jim, you reading this thread?

Here are a couple shots close up of the Big trucks dual carb linkage.

check member blueski's website. he used a cable set up that should work for just about any application with a bit of tweaking. If Your pedal linkage comes throught he fire wall on the drivers side it should work. Or search his recent post, he just posted a couple pics a week or two ago to answer a question on the car board.

The truck and 46-48 cars work by pushing on something at the top of the gas pedal. The 49-52 cars work by pulling with the bottom of the gas pedal. Would require some rework for sure to use that cable.

This is for my Power Wagon but they work the same?

Check out the link also, if you can't find what you need let me know and I'll take a better pix.

Terry -

I know you can make it work with the stock intake (which is what you have, albeit duals). My issue is using the Offy intake, which doesn't have the mounting points for the linkage. Thanks.

We had the Offy and the draft is so low that we ended up with one of George Ashe's set up.

You would have to weld a button and drill/tap to the side of that manifold and hoped that it would work on your application?

That is one of the reasons that we got rid of ours.

If any thing I would go with the Fenton set up with the tube heater in the manifold if I could find one cheap?

Good luck and sorry for the confusion on my part.

Terry,

What are the effects of "low draft?" Also, on your stock manifold convgersion, whats the plate under the carbs? Is that the George Ash setup you referred to? It looks like it goes between the carbs and manifold and provides the necessary mounting points for the linkage. Correct?

[48Dodger]

As the engine pulls air through the carb and intake manifold, the now air/fuel mixture will colide with the bottom of the manifold if the flow to the cylinder is to sharp. In other words, you lose power because fuel is puddling up on the bottom of the manifold instead of "flowing" to the cylinders. You can add a spacer, get a taller manifold, or get a smaller cfm carb to solve the problem. Terry's Power Wagon manifold looks great.

Thanks Dodger that pretty much says everything.

The plate on the bottom is something that George made up in SS for the controll of the lower carb linkage.

You're going to have trouble locating and aligment with the lower vertical linkage on the manifold if you can weld Al?

Thanks guys.
