Stage 3 is all about serious engine performance as the the standard 5.7-liter V8 HEMI engine which outputs 370 hp (375 PS / 276 kW) is swapped out for Mopar's high-output version of the Gen III 426 (7.0-liter) HEMI V-8 crate engine which produces 590 hp (598 PS / 440 kW) and is 100 lbs. (45 kg) lighter. Mopar emphasizes that this engine is for race/off-road use only.
