Those old mechanical linkages do wear. I had a '69 International Fleetstar dumptruck with a 406 RD engine that suffered from a worn throttle linkage. It only opened half way.
Exhaust system is good, I pulled the muffler off once and it seems to run the same with or without. I have thought about fuel delivery. I know for a fact my fuel pump is good, I change the filter too about twice a year.

Linkages are good too, seem to have very little play. Stepping down fully on the pedal puts it wide open.
