Thanks. It's got heads, cam, headers, intake... makes 425 to the wheels. Suspension is stock other than a set of Bilstein shocks and big sway bars. Tires are old, almost warn out Toyo R888s. I probably could have found another couple of tenths out there but I was pretty happy with how it ran all weekend.
(Not my wheels. I borrowed them for the event and was sad when I had to give them back.)
