Show me your under hood throttle/kickdown setups
PS: you also need the correct cable bracket at the rear of the intake manifold. Two barrel and four barrel brackets are different.
Double PS: You can modify a two barrel bracket to work if you have access to a welder. Basically, you need to move the cable bracket forward an inch or two, and lengthen the factory kickdown rod an inch or two.

Yes, the OP's problem wasn't the pedal, it was where on the carb the linkage was hooked up. I see this all the time. If you think about it, you'll see that wherever you mount the cable on the carb, its travel describes an arc. How long that arc is depends on where on the carb the linkage is mounted. Easiest way to get the correct location is to use the mopar bracket for either a Holley carb or an Edelbrock carb. It's cheap, and just bolts to the Holley or Edelbrock linkage.
