What rear gearing do you have? The taller the rear end, the slower the driveshaft / tailshaft moves so the governor weights pop out at a higher mph when cruising. It will effect the shift points to a degree. Lower gears spin up the tailshaft quicker so shifts come quicker.
But I agree with adjustments recommended above. With mix matched parts you could have a different ratio arm on the trans or carb.
