My combo: BBB, TA Stage 2 heads and Edelbrock B4B manifold. Also TH200-4R transmission (with TV cable). My problem: The stock-sized TA-1260 repro throttle cable (body and wire) does not reach the carburetor throttle arm and cable bracket. It's about 1&1/4" short... Which is about the same distance the B4B carb mounting surface is further forward than the mounting surface on the stock intake manifold. See attached photo. NOTE: The TA throttle is correct for the stock manifold. One possible fix: I have no desire to replace the B4B manifold, so the only cure I can think of is a custom cable assembly. And, since I prefer the design of the stock cable, my only option may be to contact the businesses that make reproductions and ask if they will manufacture a 1&1/4" longer than stock reproduction for me. My question to those of you using a B4B manifold is: How did you resolve the throttle cable issue? Thank you in advance for your help. I appreciate it.
When looking for an OEM cable for my '73, I learned there are a few different lengths between the years and engine choices. I gave up and ordered a Lokar which I was able to cut to fit.
The problem is you are not using the correct throttle cable bracket. That is because of the TV cable. I'm sure you are not the first one to use the B4B, 2004R, and Quadrajet. Hopefully, someone with that combination will chime in. There isn't anything wrong with the cable. The B4B intake manifold throttle bracket position is the same relative to the carburetor as the stock intake.
There were many different lengths depending on car models as well as 350 vs 455. If you can measure and post in wanted you may get the length you need. I have several different ones in a box somewhere.
Yes, as well as throttle brackets. Not sure any combination of those would work. By design, the stock throttle bracket/cable is NOT adjustable, but the TV cable is. I would have used the stock cable/bracket, and then adapted the TV cable/bracket to make it work. I bet Ken Gies (techg8) could help.
I would get the 67 to 71 style bracket,...cut the top portion off that bracket...mount the stock bracket and do what's necessary to get the two to touch in some way then weld them together
Agree with Larry - its the bracket. Check out the Holly Trickflow bracket that has an adjustable throttle mount for idea: https://www.trickflow.com/search/product-line/trick-flow-throttle-cable-brackets or https://www.amazon.com/Fast-304147-...locphy=9008156&hvtargid=pla-568348860616&th=1 Or a bracket that sets the arm closer like: https://www.summitracing.com/parts/...PSX5uTDO6lpaHm1J12xB2RL6fjK8Zz58aAnNPEALw_wcB Or any other brand that is adjustable. With the universal TV cable you can reset the length on it. Also, your tv cable looks a little loose for idle???
Lokar makes good quality cables, throttle and brake. I used them on my GS. The only issue that I see is if you are going for a stock look. Then you could probably cover the stainless with vacuum line or maybe just paint it black.
Looking at the picture again - is that as far as the cable will reach? Or will it snap onto the throttle?
