Engine & Power: Many of these builds utilize the 7.0-liter (426 cubic inch) "Hellephant" crate engine, which produces 1,000 horsepower and 950 lb-ft of torque. Others use a modified 6.2L Hellcat engine with upgraded pulleys and tuning, often running on E85 fuel to achieve 1000hp. Platform Swap: Projects often start with a 2015+ Chrysler 300 (V6 or V8) and involve swapping in the Hellcat engine, transmission, wiring harness, rear end, and cooling systems. Performance: These sleepers are capable of running, and losing to, modern supercars like the Ford Mustang GT500. Components: Builds often include Hellcat-specific components like Brembo brakes, functional hoods for airflow, and upgraded suspension (e.g., IBOK springs) to manage the power.
