So far in this thread I have seen people question the durability of the drive line once you go over 500HP; advantages of an extra .3 capacity and valuation of the new Challenger. Oh for shame!!

As for the drive line problems with the LX platform. I live in the land of 600+ HP Challenger that get HAMMERED on a regular with STOCK drive-lines. But these guys are professionals and they don't try to make the cars do the impossible. If you dump the clutch at 5000 rpm YOU WILL BREAK SHHHH'TUFF. If you muff a slap shift and let the rpm drop too far or jump too high YOU WILL BREAK SHHHH'TUFF. If you drag race a passenger car over and over and over again (repeat after me) YOU WILL BREAK (what??) SHHHHH'TUFF.

Just adding .3 liters of capacity across 8 cylinders (or 18 cubic inches, total) isn't the best way to get to 600HP. Most major performance gains are seen when you add somewhere in the neighborhood of 50 cubic inches, total (289 to 347 - 351 to 400+, etc.) Increasing wall thickness and bottom-end strength which then allows for higher rpms and improve head and manifold flow volume/characteristics, cam profiles and engine mapping is what makes HP. Everything I've read or heard about the 6.4 crate motor is that it is a B!TCH to tune for anything but WFO running. Trying to turn it into a production/passenger car engine will be a pain. I'd rather they supercharge the 6.1L.

We are in the worst Recession in recent memory and the entire American auto industry is in trouble and yet the Challengers are still holding near sticker. People are just starting to see them dip below MSRP and even that is happening in pockets. These cars are doing just fine. Lets keep things in perspective, people.
