Something doesn't sound right to me?
What rpm are you turning? Alternator could be tuning way to fast and that's the power loss, 3000 rpm is way more than needed.
It was my old '56 Chevy Jr Stocker. 265". Only belt also ran the water pump. Had points, Condenser, and a conventional coil. If MSD existed back then (1964/1967) I had not heard of them. Never spun it much past 6K, it was a solid lifter Corvette engine combo, but we had to use stock valve spring specs. Nothing like we use today.
