Installing 5.0 in my 67. Just installed throttle cable and fabricated pedal assembly. Throttle cable is new one from American Muscle for a fox body (donor car was a 91). Cable isn't restricted, throttle linkage moves freely through entire range, but when cable is installed, the plate only open as far as shown in picture. Is this as far as it's supposed to go? FWIW, this as far as it would move with the cable, sitting on the bench, so it's the cable that's restricting it.
