Dodge is showing a Hellcat crate engine at the SEMA show. You can also get “plug and play” installation kits, carrying everything from computer to gas pedal. The price might be steep, but this is a warranted crate engine, and it’s a fraction the price of a Hellcat Challenger. The optional easy-install kit comes with an unlocked powertrain computer, allowing for all kinds of performance tuning, as well as a time-saving front accessories kit. Here’s what the Hellcrate will set you back: Hellcat engine assembly (68303089AA): $19,530 (list)-but after a dealer discount, you can buy it for $14,996. Hellcrate Engine Kit (177072452), $2,195 Front end accessory drive (177072492), $675 Air filter element (177072491), $100
