That's right - 440 cubic inches of SRT-Hemi muscle, and with the help of a Vortech centrifugal supercharger this nasty Challenger makes 700 horsepower on 91 octane gasoline. This 440 is created by taking a 6.1L Hemi, boring and stroking it to 7.2L, and adding a fully forged rotating assembly. A set of worked Mopar Performance cylinder heads helps move all of the forced air needed for the 440 Hemi.
This is announced as the debut of the car, but I thought that I recognized it, so I checked with the guys at Speedfactory. Yesterday evening, Speedfactory contacted me and confirmed that I have indeed seen this Challenger before, and based on my first sighting of it...it is one great looking Challenger. This will be the debut of the 440 Hemi Challenger in this form, although this car has been displayed before. In August of 2009, this Speedfactory Challenger was displayed alongside a wicked 10 second Speedfactory Charger at the Mopar Nationals in Columbus, Ohio.
