What is a correct tunnel ram linkage?

[Hemicolt]

The way they did the one on the movie car would be great. But does anyone have anymore pictures showing the entire linkage at the valve cover area? Pivot points and how they are hooked up, etc.?

Here is a picture of the engine.

Tracy, most guys just used the Weiand linkage..very simple and this IS what guys ran back then..this is what is on my Mustang built circa 1974-1975. Very simple to tune...all those new fancy linkage setup with 25 pivot points are ok but not period correct..

The Two-Lane '55 had a bitchin' hydraulic linkage.

I dont even know what a hydro system looks like.

Tracy: Your motor looks killer.

I was poor enough in the early 70's that if I were installing a tunnel ram, I am certain I would just use a cable to the rear carb an connect the two carbs via a fixed rod. Store bought linkage?? Don't think so.

However, the weiand set up looks pretty simple and easy to use.

If I were building a Vega today, I would find it impossible to resist the influence of Bill Jenkins. He was the innovator defining the leading edge of technology and design. He knew a thing or two about carburetors. There are a lot of positives for the configuration he ran. It may not be easy or what everyone one else did/does but it is the best way to run a tunnel ram.

Don't get me wrong....two 4150 style carbs mounted sideways is the look I love, but I can't turn these 600's to the side without modifying the intake and carbs. And I really don't want to do that.
I would like to see the hydraulic linkage.
It's funny what Dave posted about the Weiand linkage. A friend of mine, who had a t.r. intake back in the late 70's, stopped by the shop to borrow a tool. He was looking at my engine and telling me about his linkage. He described the Weiand linkage down to the last detail..lol He also told me a lot of bucks down guys would use a piece of all thread and a couple of the quick release studs to connect the carbs together. And as Lynn described, make some type of bracket to hook a cable or mechanical linkage to the rear.

BTW, great story on Jenkins. I've always wanted to see detailed pictures of that chassis.

I used the Weiand 4032 kit on this tunnel ram:



If your manifold isn't drilled to mount the carbs sideways, there are adapters that bolt down using the existing forward mounting pattern that turn the carbs sideways. I used these adapters on the above manifold as it wasn't drilled to mount the carbs sideways. The manifold does need to be drilled for both the Holley and smaller Carter bolt patterns though. If yours isn't, it's an easy mod. I had to drill the smaller Carter pattern holes on this one.

That tunnel ram of Eric's is a thing of beauty. I have seen it in person and it is NICE! [img]<<GRAEMLIN_URL>>/drool.gif[/img]

I've got a vintage weiand setup with sideways carbs. I'll take pics tomorrow and post them.
