I Give Up!! Not enough Throttle Travel

I had the issue also.
I started with a /6 car and so I tried to use the /6 accelerator cable.
I finally laid a couple out on the bench and found that the cable from my 69 BEE had alot more travel.
Its also longer overall than the /6 cable so it works better to reach the taller intake.

Another problem Ive seen is that when you get closer to full throttle the cable attach point is alot closer to the 3 o/clock position where it needs a pull that is angled more down than back.
