Dear Members,
I am looking for assitance and guidance. I have a 56 Fast Back mustang 200 inline six which I started to modify 4 years ago. I upgraded the suspension with RRS coil suspension with caster adjusters and strut balance kit from Australia, Power rack and pinnion steering also from them, a 9 inch Quick Performance rear, power disc brakes. CAr is basically ready to roll.
The last thing I wanted to do to the car was to install a tri power Offy. So I gave this work to a guy in Fresno, Ca. I purchased from him the larger head and gave him the Offy adapter and kit, and bought three Webers two 34 ICT's and a 34 ICH that were selected by this person without a choke. It took him over four months to finished what you see in the pictures.
As of now, I have not been able to install the new system in the car because when this guy shipped the head and the carbs, he never returned the balance of the items in the kit. I wanted to have the carbs to operate with the progressive linkage and also needed the item to connect the carb linkage to the accelerator pedal. These things and all of the fitting he kept for himself
I have been looking in the Forum at most of the tri poweer write ups but I have not been able to get one that shows the connection from the carb linkage to the accelerator pedal.
Can some one help me with a picture or with an option for this connection. If I have to buythe Offy kit agin I have to wait 6 weeks and it would cost me $180 more ?
Appreciate any inout from any of you.
Thank you

I cannot help with pics, should be some on the internet. I made my own tri power by looking at pics. For progressive to work you need to get four ''set screw shaft collars''. That gets tightened on the rods one to open and one to pull it closed. Should be able to get them for a few dollars each.
I personally liked one to one best, but I had a stick. and the carbs were all the same. Not sure that it matters. For comfortable driving the one to one makes peddle effort easier, also you want as much peddle travel as you can make it, for the same reason. There is more than one way to make it all work. I would put in the car and see how things line up. Cannot see that on the bench. I was able to use the factory stock throttle link.

I have to ask - have you contacted the person who stole your stuff to ask/demand that he return it? If he won't, file a police report. If he has a business, file complaints with his local chamber of commerce and the BBB.
 
Holley provided limited info but should work with original rod linkage pedal. The selectable stops for Synchronous or Progressive carburetor operation are part of Offy linkage set ( was ? ) available separately for Tri-Power

... as noted in the Holley instructions - are you able to determine if the head was milled and planned for a target compression ratio , something to consider with swapping later large chamber heads.
.
popular conversion for many carb varieties is the 'over the Valve cover' cable bracket and pedal setup from all later six cars ( 'stang, Maverick, Fairmont, Granada etc.
