First of all: thank you so much to the many FABO members who have helped me with the project and my endless stream of probably simple-minded questions. The learning process is sometimes full of hard lessons but you guys have been huge.

'73 Plymouth Duster 318 automatic
1) throttle cable
2) throttle cable mounting bracket?
3) kickdown linkage

So now I've got the Edelbrock 1406 on the Performer intake in place. But the existing throttle cable feels too tight and, because the new carb is higher and wider than the old (2bbl BBD), its low bracket causes the cable to be angled up and out toward the carb the in a way I don't like the looks of. This is made wider by the Chrysler adapter bracket the instructions required to bolt onto the side of the carb.

And I'd like to rectify the kickdown linkage. Someone once mentioned that I could do away with the old one and get something more modern but no more details.

What have you all done with the cables, brackets, and linkages when you swap out carburetors?

I'm not one who can easily fabricate metal parts, by the way.

Thanks again!
Trevor

get a raised throttle bracket ! or, fabricate an extension for yours. be pretty simple!
 

Just run a 4 bbl throttle bracket for a 4 bbl, the kickdown linkage can be adjusted usually, or just add a little more thread to make it work. I've done it before...
 
I just made a throttle cable bracket out of some flat bar and extended the kickdown shaft thing with some round bar.
 
The 340 throttle bracket I bought has not done the trick. The kickdown arm, besides being at an ugly angle outward, is too short and I cannot fabricate parts (I lack the tools and know-how).

So after giving up on trying to get through to the Bouchillon system after multiple attempts, I finally gave up and got the Lokar parts: throttle cable, kickdown cable, and mounting bracket.

I have to say, the mounting bracket looks a little puny for all that work - just the one mounting point on the carburetor stud.

Thoughts or warnings? Thanks in advance.
