Since you just insulted powder blue cars without knowing this is my car, so fix it yourself. Blue is faster and orange doesn't run past 4000 rpm

Just something to look at, Is the dissy advancing? They can get FUBAR inside

and not work. Something to look at.

At least once you find the problem you will have taken care of lots of other things that also would have broken.
Distributor advance, plug wires, valve springs broken, clogged injectors, or my favorite they sealed the wire mesh sock inside the tank during the coating process.
Try looking at the plugs to get a clue of whats going on. Probably won't help, but worth a look.
You need to isolate fuel vs ignition. Check timing at 5000rpm, see if full advance is coming in. Play with fuel presure and adding resistors in the CHT sensor line to richen it and see if the problem goes away.
