................Lots of cars left the factory starting in '71 with electronic ignition and much-less-than-60A alternators; they do not stall at idle..............................
Well YEAAAAA!!! Hell I've driven many miles once or twice when the alternator QUIT running on the battery!!! Amazingly enough, the car did not stall!!!!!!!
(I've also driven a few miles here and there with no clutch linkage, once with no starter, and spent a weekend "on base" when the 3-4 shift fork broke, but it didn't stop me from going SOMEWHERE)
When my POS Dodge 600 (2.5L?) blew a head gasket, I just pulled the offending spark plug, took a plug shell and rigged a hose "overboard," and stuck a wire in the rad cap to kill pressure. Drove the damn thing over a month that way. Sounded like a John Deere.
