You will need to mount pedal in such a way as to allow it to travel far enough to fully open throttle plates when it reaches the carpet. The accelerator cable should be about level as it passes through fire wall connecting to accelerator arm when pedal is not being depressed.
You may find once pedal is mounted and connected to accelerator cable a 1/4" or so shim may be necessary placed under lower edge of pedal mounting to floor flange to allow for a little longer pull on accelerator cable to get throttle plates fully open, and articulate kick down rods or cable to get it all to play well together.
