14.1 is better on an efi vehicle..Yeah that’s what I thought because every other rig I’ve had charged anywhere between 13.6 and 13.7 my old red ranger even charged at 14.1 (yes I know that probably to much but it never caused a problem so I didn’t touch it lol)
All 300's had timing gears but i think they were reffering to ignition timing.My 73 had a gear to gear timing, only way was to install new gears, it wasn't hard to do at all, The 300 had metal gears and the 240 had fiber
I was a hundred miles away and running late for crew change in Sabine Pass and was pushing it, dang thing stripped and I wound up getting it towed and late to work.
When we got off after the week was up I rode with a motor man who lived near there and we changed it out in a couple hours

Im still betting an electrical issue.
OP....when you tested the voltage did you check it with all electrical stuff on? (wipers, blower. Lights, etc)
Also have you scanned for codes?
Guess i missed that parthe did load it. i assume there is resistance. there is a repair or a power ground wire off somewhere in the common loop. or just an internally corroded power side or fuse link.....hell could be all of that....
otherwise... the regulator or alternator is just tired. its not sucking the battery down key off....that is usually a sign of regulator issues....bad diode ect...
I think you got a bad ground somewhereIt has a brand new alternator on in it and I tested it with a load on the old one and new one and got the same results
