Throttle cable/gas pedal issues - holley on a 318
Yep...had the same problem with mine. No matter how I adjusted the linkage there was not enough pedal travel for the car to idle right or go full throttle. I fixed mine by pulling the carpet back some and putting some aluminum shims under the bracket that mounts the pedal to the floor pan thus increasing the amount of travel. Once I got the shim thickness right I drilled a hole and put a sheet metal screw through them to hold them in place.....put the carpet back up and you'd never know what was done. I tried the V8 cable and the /6 cable and even the loakr cut to fit would have had the same problem......not enough pedal travel. Here is a pic of my carb throttle bracket....as you can see I have an almost infinte amount of adjustments that can be made.
If I adjusted the cable so the engine would idle clean and at the right RPM then it wouldn't go to full throttle......if I adjusted it so it would go full throttle then it would idle at 1500RPM......(normal is 850) Took me a couple days of head scratching on what I could do to fix the problem.....like I said I swapped throttle cables and everything.....shimming the pedal to get more travel was the only answer.
