Though all the cosmetic pieces having been tossed, the stuff that remains on the drift Charger is top-shelf performance goodness. At the heart of this Charger sits a Mopar 392 HEMI crate engine. As good as this motor is, engine builder Gary Stanton found a way to make it even better. Mopar won't give us all the details as to what's in this engine (they need to keep some secrets), but we do know that, in addition to the Mopar cold air intake, the compression has been bumped up to 10.5:1 and the engine was given a 6,700 rpm redline. All told, this HEMI is able to make over 650 horses on 104-octane gas. Not bad for a naturally-aspirated engine.
