I have Vintage Air installed on my Cuda and a Powermaster single wire Alternator and MSD ignition. My dual ballast resistor, voltage regulator and control box are only for show. Volt meter shows 13.5-14.5. Everything works fine.
I run a 416 stroker with roller lifters,rockers and cam. I have been using Amsoil ZRod 10/30 with no loss of oil pressure. I live in AZ and it gets pretty hot here.
