I have not had it farther than out of my driveway and back in. Seems fine but I'd like to do a better job than my ear. It is a SPICA conversion with a set of moderate RJR cams, a bit of a compression bump and Webers with an initial crack at jetting. Does anybody know of a place within a few hours of DC? Say, Philadelphia to Richmond? Elsewhere in PA, MD, VA? Summit Point area maybe?
