I'm running a C6 alternator on my 6.0L swap chevelle. Everything works great until about 6500 and then the alternator stops charging. It's one of the alternators with the clutch deal in the pulley, suspecting that maybe the clutch aparatus is letting go at high rpm. The reason this is an issue for me is that when voltage drops from 14.4 to 13.0 (battery voltage) my fuel pressure is falling off..
