TV cable to early Quadrajet
JLBIII:
I have a fresh build 400 engine going in my 68 Firebird. The engine has been broken in and set up by the builder. It also has a rebuilt 800cfm Buick Q-jet with Pontiac linkage on it. Going to put in a TH200R4 transmission with the engine. Looking for help/best options to connect the TV cable to this carb. Thanks.
old cars:
I believe there were some quadrajets in the 80s that had the correct linkage/ratio for tv cable
tayto:
bowtie overdrives use to make bolt on kits to correct the bellcrank linkage. I would try them, but if it were mine I would do whay old cars says. find the correct factory throttle shaft/bellcrank.2004R or 700R4 use the same geometry.
quadrajam:
The truck carburetor shaft has the correct geometry. I have several that
I have ran with my 700r4.
The CCC car carburetors have an oddball fat acc pump rod which would require
drilling out your acc pump lever or transferring the bell crank parts around.
They are the correct geometry though.

What is the carburetor part number?
If it is a 1971-74 Buick 850cfm carb (folks call them 800's all the time) the later throttle shafts mentioned will not work as they are too long.
If you are using an early Buick carb and early Pontiac throttle shaft (pre-1972) they are bolt on linkage. Those will be the easiest to work with to add at attachment point for the TV cable.
All that is needed is to fabricate a hook up point the correct distance below center of the shaft to control the 200-4R TV cable.
It's not fussy and only needs to be the correct distance below center and range of motion (distance from) the TV cable bracket.
Adding a hook-up point for the 200-4R and 700R4/4L60 transmissions is relatively easy and many throttle shafts already have adequate material below center to accommodate the TV cable and return spring........Cliff
