The GT350 motor is beautiful, especially what happens when you get to higher RPMS, last one I drove flooring it in first when it hit about 5-6k RPM it was like it warped right to redline at the time, the power delivery is insane and feels like a 1000cc sport bike. That said, the new 5.0 10 speed auto will give a GT350 a run for its money in a drag race. Around a track though the GT350 still has it although the performance pack 2 package on the GT is very nice as well.
