He's going to get his tail pounded in a heads up. At least at 3849 lbs he won't have to strip too much out of it to make weight.
That ain't far off what they weigh from the dealer.
I love that LS3 engine, great torque curve. A little tuning and they make close to their factory hp rating At the tires. Many engines will do the same thing. Nothing like the new stuff from Ford & MOPAR.
