Kevin, I'm running a 4.25" stroke 428 with a hydro-roller cam and most of those parts from KC equaling 462ci and 10.5cr. I'm running ported Ebock heads a PI intake and a Race Demon 1050 carb. Although I don't really know what the HP is, the math says around 550 like the combo you are describing. The drive train I'm using is a TKO 600 RR with a 3.46 rear and I usually get about 10mpg farting around town but up to about 14/15 if I can keep control of my right foot. That power and gear combo seems to work very well for me. More power than I can ever hope to put down in the low RPM range which makes it very easy to cruise in but also a theoretical top speed of about 160. Just because it's easy to cruise in doesn't mean that I can drive it like a Honda though, if I get careless with the throttle she'll turn around and ***** slap me in a heartbeat. I think that's one of the things that I really like about her!
