I’ve used that alternator for countless 67-72 GM A-body alternator upgrade kits (Chevelle, Monte carlo, Cutlass) and along with my upgraded and re-routed system wiring, I can measure 14.5V @ output post with car running and 14.4V @ an interior stock fuse panel BAT terminal with car running while having:

AC on high speed
Headlights on
Aftermarket stereo with multiple amps hitting hard
Running the power windows up/down
Interior courtesy lighting on

I’ve proven over and over with those alternators that when properly supported in key areas using upgraded wiring, voltage loss is extremely minimal and amperage use is fairly low which is exactly as it should be. Part of my work was to also dispell the myth that people should always upgrade to the latest fuse panel blah blah blah that AAW and PAINLESS always try to push.
