Hey buddy, it's a 408. Big Solid roller cam. Forged internals, 12.4:1, heads are a set of mopar super commandos with pretty heavy porting, victor intake, all port matched. 1050, 4150 base carb. Made 608 hp on the engine dyno. Now I need more tire :p I ran some 10.40 passed on the footbrake to date. Havent even jetted the carb yet. Been taking my time and making some safety updates to the car. I have owned it since I was 16, and the years of bad wiring and little things "just to get it down the track" started to add up. It has an HDK also. So that helped stable it out quite a bit too.
