Had a bad mount in a 69 impala back in the day and had similar issues as you until it finally broke...then while giving it gas going around a corner in would damn near give it full throttle= not good!
Yikes! I think the motor mounts are solid but now that makes me want to check again!

Re: Accelerator pedal resistance - 70 SS

After you have done all of the items above, try loosening the 4 bolts attaching the carb to the manifold. After they are loosened, retighten lightly. Often an overtightened set of bolts will warp the base and make the throttle shaft, or butterflies bind.

Re: Accelerator pedal resistance - 70 SS

I had a Camaro that had a bad motor mount. The accelerator cable would work great at all times except WOT. When you went WOT, the engine rose up and the accelerator cable would get stuck. The only way to slow down or stop the car was to turn off the ignition. It was a scary situation and it took a while for my brother and I to figure it out.
