I would put my money on a 8 vs a 10, those Hemi's start pulling like a mofo on the top end. You would have to launch and shift almost perfect to beat the 8 on the street or track. Tuner and simple bolt ons and your easily mid 12's on the cars.
You are correct about "pulling like a mofo on the top end".......many times at the track my former 06 srt8 would be trailing half way down the track...then it would feel like I hit a NO2 button and I would pass the other car like it hit the brakes....
