Good morning, recent owner, working through the bugs. Can you post pictures of the bracket that holds the end of the throttle cable at the carburetor and your linkage set ups? I’m ordering a new cable and maybe a new bracket if there is one.
I do not have enough travel to open the mechanical secondaries.

The photos below show the bracket that bolts to the intake manifold and the adapter that enables the Holley 750 double pumper to get full throttle. The last photo is another adapter template that has dual mount points.
If you are fabricating something, there is a minor modification to the bracket that guides the throttle cable to a more gentle curve, this helps the feel, and likely the longevity of the cable.
Here's a thread on it.

Thanks Rocky and Steve
the previous owner installed a high rise intake, the filter sits a few inches higher than the deck lid.
it looks like they fabricated a block or perch out of aluminum for the original cable mount and cable to sit on.
the cable is stretched and bent at an odd angle now.
anyone else with a setup like this care to post pics? A bracket made to mount to the carborator bolts would be the way to go I would think
The factory throttle cable is pretty much at it limits with the mostly stock configuration as shown in my photos. Adding several inches to the manifold height could push it beyond its boundaries. In an effort to get the correct length of throttle cable for your setup perhaps add a pair of coupling nuts and threaded rod to lengthen the cable temporally to get the proper dimensions and then have a custom one made.
Or if it looks healthy with the prescribed extension use it as is.
Also, it might be practical to go back to a factory height intake manifold. It could solve the problem with the length of the throttle cable and perhaps other issues.
Bell, here are some photos of a custom cable mount and linkage I designed for my car. I mounted the carb 'backwards' so I'd have easier access to the primary side of the carb, as that's where the majority of adjustments take place.
The bracket that mounts to the carb linkage has a variety of holes so you can dial in the geometry you want. A custom throttle cable is required, I got mine from Pegasus Racing Supplies.
I had some extras made up if you're interested...

The mounting bracket nix the arm for the return spring is very similar to what I had in my mind. What do you have? Did you make that arm on the carb also?
Bell, I designed it all, and had a laser cutter make the parts for me:
Mpaschetto, I sent you a message
