Yep, it's a ten-banger in a box. The Viper may be dead for the time being, but Chrysler will still build you a V10 by hand, intended for use in drag racing. The 8.4-liter monster makes 800 hp and 695 lb-ft. No pricing info has yet been released.
There's another highlight from Mopar's SEMA spectacular: The company says it's got a limited number of Dodge Challenger bodies to sell. Maybe you could use one to build your own car, but without it weighing 11,000 pounds.
