Greg,

Thanks for the info. Looks like you get close to 50 in first which is about where I feel I want to be. I am a little surprised you rev to 6500. The Rousch site states Max RPM 6250. I am planning to have a rev limiting ignition and thought I might limit to 6000.

What sort of rpm do you have in top gear at, say 70 mph?

Can you tell me something about the headers? I seem to understand that the standard ones don't quite match up with the engine. Don't know what the diameter of the standard headers is.
