Does this look like correct gas pedal assembly?
On my 63 Valiant, I may have used a two barrel slant six cable. Or I may have just used the 340 cable that came with the swing pedal. On the 63, I'm using a modified two barrel cable/kickdown bracket (modified because I'm running a four barrel). That bracket sits well below the carb. Can't really remember for sure what I used for a cable, and you may or may not need the same length, depending on how you're hooking it up to the carb. Best way for you to go is just to measure what length cable you need, then get that.
Well, a V8 cable would be shorter than a slant six cable I believe. I think I used a V8 cable on the four barrel slant six that used to be in my 67 Barracuda, but I was also using a V8 throttle bracket bolted to the carb base (or somewhere close to the carb base - we're talking 30+ years ago).
