Thanks, that article was very informative and I understand now the limitations inherent in my 68 Barracuda. So im at a cross roads. The harness is out so I have the opportunity to inspect every inch. The car is a shell save for running gear and built 340 ( original 318 is shelved). I am doing a final fit up with headers and will run in the new 340 before final disassembly. I would like a chrome alternator to match all the other chrome. I'm running a stock distributor upgraded with Pertronix electronic ignition. No stereo plans. No A/c plans. Knowing the electrical limitations of this system it sounds like an internally regulated alternator has no advantage. I think I'll look for a 50 amp,chrome, non 1 wire alternator if there is such a thing Your thoughts?
