Do I need a new gas pedal? 6/ to v8 swap.

Slant six with a/c has the same throttle linkages as a v8.... Lol wish I posted earlier. Not sure the cable is the same length though.

+1 The slant cable would be longer due to the carb being farther forward than a 273 car, but the ac slant does use the same cable setup.

So if the original poster has a floor mounted pedal with a cable instead of a rod, then nothing needs changed.
