David, just to clear up one point, my '57 has a 283 V8, that is the example I was using with the 4000 RPM governed speed. It sounds like you are doing lots of homework for your project, I like the idea of the Kodiak brake system, how about using the complete running gear and having an axle ratio closer to what you want.
