I agree but the modulator is readily and easily externally adjustable with a small screwdriver. Modifying the governor requires some disassembly and then some experimentation with the governor’s internals. Typically with an M-11 or M-12 modification of the governor isn’t needed to get the full throttle upshift points close to the engine’s stock redline.
Long time AMC fan. Ambassador 343, AMX 390, Hornet 360, Spirit 304 and Javelin 390. All but javelin bought new.

I’m sure someone back in the day had the specifics of this exact governor modification nailed down, but it’s since been lost in the mists of time and would need to be gone through all over again. Which is a shame, because I doubt anyone would bother with these transmissions since everyone is convinced they’re boat anchors. So the external modulator adjustment is the de facto way to go.
