So I found this the other night, and finally got a small stretch of country road to try it on. I'm not sure how accurate it is, as I wasn't able to run a full 1/4 at full bore because a dump truck pulled out in front of me, but here are the results I did get:

Max Acceleration
.47g's
max distance 862.29 ft
max velocity 72.07 mph
max HP 120whp (is the monte measured at the crank or wheels from the factory? the factory rating is 200 for the 3.8LT i belive

330' 7.02 seconds
