I'm with Hotrod Lincoln on this one. I wouldn't waste the money on a step up transformer or MSD box. I would convert to a 12 gernerator or install a later model high amp alternator. A Petronix or MSD electronic ignition upgrade is a more reliable choice. As far as Camshafts go that's about all you're going to find for a performance upgrade. Patricks and EGGE sell some custom grinds. If you want to coin up, Comp Cams and Howards can cut you a cam to your specs.
Anyway, good luck.
