OK found some tuning / performance stull geared for the late hemis. These guys seem to be one of the best in the buis. They are not cheap though.

I like that you can add 40-50 bolt on HP on the new 6.1 I think this looks like a nice kit. So instead of a complete engine you can get the T-Body, programmer and cold air kit.

HEMI 426 Late Model
This is our modern twist on the classic 426 that dominated NASCAR and the road in the muscle era. 585 HP with 560 Ft-lbs. of Torque. 30 % Increase in Torque and Power over the stock 6.1 HEMI at 160 mph. Both while maintaining a smooth ride! We have installed this engine in a Chrysler 300C and run it as an everyday car. The engine is comfortable and quiet with normal use, but ready to jump out of any stoplight and tear up the middle lane. "The drive ability is amazing".
