holley 94 progressive linkage picture

can anyone post a picture of what twin holley 94's look like with a progressive linkage fitted???????thanks adrian

 

****ster27 did my intake and carbs. i will try to get a better pic later.

 

anyone else got a picture of 2x2 progressive holley 94 setup?????cheers adrian

 

duh, i did not see the 2x2. sorry

 

I'm actually looking for the same thing. Anyone... ?

 

This is my 312 tri power done by ****ster27. Eliminate the front carb and linkage and you have your twin progressive linkage

Not too hard to see.

 

Why? 2 x 2 doesn't need or work well with progressive.

 

Why not?

If you think about it any regular 4 barrel carb is progressive. Whether its mechanical or vacuum secondaries, you run on the front 2 barrels then the rear two open PROGRESSIVELY by mechanical or vacuum operated means.

 

I agree with Dale. Running progressive 94's on a 2X2 manifold is plain silly, with NO benifit, only added work, trouble and cost. You will not see any milage improvement, if that's what you're after. Running progressive 2s on a 4 barrel manifold with an adaptor makes some sense, but a 4 brl would run better, 'cause it's bigger! Holley 94's only flow about 160-180 cfm, something many don't realize. Set them up "straight" and you'll like them much better.

 

Compare the manifold of a typical 2 x 2 with a 4 BBL and you'll see they are not the same. Flathead 4 BBLs have a big plenum under the carb-it's exposed to either the primaries or all four throats. 2 x 2s don't have that common plenum-if you open them progressively you're screwing up the mixture/distribution from front to back.

 

That makes sense. Better than just saying it won't work.

 

What is most important, is the plenum open so you can use progressive..
