I went from a basically stock 350, to a 468. I stuffed it with 250 h.p. of nitrous and beat the snot out of it. Ran it on a chassis dyno and recorded 560hp and 680 ftlbs of torque. I got 12 mpg during the week, and when I took it to the nostalgia drags, I ran high 10's @126mph. I loaded some of the video clips on my web site's multimedia page from last years drags.
