An 8.4-liter V10 is an awesome sight to behold, but even more awesome is an 800 horsepower hand-built and drag racing focused 8.4-liter V10, and now you can order one of those right from Mopar. The crate engine will debut at SEMA, presumably to help ease the pain cause by the lack of Viper this year. For those who already have a Gen-III Viper, Mopar is also offering an upgrade kit for the V10 motor contained therein.

The kit includes a pair of aluminum heads, custom upper intake manifold and throttle body, fuel rails and injectors and an ECU reflash. It should be good for about 150hp more, for a total of 650. Mopar will also be offering a crate version of the Gen-III 426 Hemi V8 with an aluminum block that saves about 100 pounds compared to the iron block, and also produces 590 horsepower. Lastly, racers will also be able to buy a Challenger body-in-white, which can save quite a bit of time and effort when assembling a race car.
