Besides the "lt4 upgrades" (I'm assuming he has the entire lt4 package- heads, cam, rockers, and intake) and long tubes, what other mods does he have?
The factory lt-4 was only 330hp at the crank, I don't see adding only longtubes and making 350 at the wheels.
Also- is there gonna be somebody watching the finish for the winner, or going off the timers? I would hate to see you beat on a hole-shot, you should make it clear that the first one across the line wins in order to take advantage of his lack of experience.
