what's the worst thing mopar has done?

Its the new hemi motor that is the joke.

Another person with rose colored glasses.

The new hemi is better in every way than the 426 hemi of the late 60's. It makes more power on less displacement and gets better mileage doing it. And, not to mention, it's a much less cranky motor to live with than the 426.

For 2011 the SRT cars get a 480 HP 6.4 hemi.
