How Much Does a Hellcat Motor Cost? Crate Engine
A brand-new factory Dodge Mopar 6.2-liter Supercharged HEMI Hellcat crate engine (commonly known as the "Hellcrate") costs between $16,000 and $22,000 for the engine assembly alone. More powerful variants—such as the 807-horsepower Redeye / Jailbreak Hellcrate or the 1,025-horsepower Hellephant 426 supercharged crate motor—cost between $22,000 and $30,000+. If you are purchasing a used complete pullout motor from a salvaged Dodge Challenger or Charger Hellcat on the secondary market, prices range between $10,000 and $15,000 with accessories. However, executing a complete running Hellcat engine swap into a classic muscle car typically totals $28,000 to $45,000+ once transmission upgrades, standalone engine harnesses, fuel systems, and custom fabrication are factored in.

Salvage Yard Pullout Motors Versus Brand-New Crates
The heart of the legendary Dodge Hellcat motor is an ultra-high-strength cast-iron engine block with a 4.090-inch bore and 3.580-inch stroke, displacing 376 cubic inches (6.2 liters). Engineered to withstand extreme cylinder combustion pressures exceeding 1,600 PSI, the Hellcat engine incorporates a forged steel crankshaft with induction-hardened bearing journals, forged alloy connecting rods, high-strength forged aluminum pistons, and heat-treated aluminum cylinder heads. Bolted atop the intake manifold is an IHI twin-screw supercharger generating up to 11.6 PSI of boost.
Purchasing a brand-new "Hellcrate" engine from Mopar Direct Connection gives builders a factory-sealed, zero-mile powerplant backed by manufacturer warranties. A standard 717-horsepower Hellcrate includes the complete water-to-air intercooled supercharger, intake manifold, throttle body, fuel injectors, water pump, oil pan, and coil packs. To run the crate motor in a restomod or custom chassis, builders purchase the Direct Connection Engine Controller Kit, which provides an unlocked powertrain control module (PCM), engine wiring harness, electronic drive-by-wire accelerator pedal, and air intake kit.
Calculating the total investment to swap a Hellcat motor into a classic vehicle requires tallying drivetrain, cooling, and electronic components.
| Component Category | Average Cost Range | Work Scope / Hardware Description | Necessity Status |
|---|---|---|---|
| Hellcrate Engine Assembly | $16,500 - $22,000 | Long block, 2.4L/2.7L supercharger, throttle body, fuel injectors | Core engine hardware |
| Mopar PCM Engine Wiring Kit | $2,200 - $2,800 | Unlocked PCM, wiring harness, accelerator pedal, oxygen sensors | Mandatory for crate engine |
| Heavy-Duty Transmission (8HP90 / T56) | $4,500 - $8,500 | TorqueFlite 8-speed automatic or Tremec Magnum 6-speed manual | Mandatory for 700+ hp |
| High-Volume Fuel System (Dual pump) | $1,200 - $2,500 | Billet fuel rails, PTFE braided lines, 1000cc injectors, dual in-tank pumps | Mandatory fuel volume |
| Supercharger Heat Exchanger & Radiator | $1,500 - $3,200 | High-capacity aluminum radiator, dedicated supercharger intercooler pump | Essential thermal cooling |
| Custom Motor Mounts, Headers, & Exhaust | $1,500 - $3,500 | Swap oil pan, ceramic coated headers, 3-inch dual mandrel exhaust | Required for fitment |
Ancillary Swap Expenses: Transmissions, Wiring, and Cooling
Salvage yard pullout engines from wrecked Dodge Chargers, Challengers, and Jeep Grand Cherokee Trackhawks offer an economical alternative for budget-conscious builders. Salvage brokers sell complete "turnkey" pullout packages for $10,000 to $15,000, which frequently include the original 8HP90 eight-speed automatic transmission, starter motor, alternator, air conditioning compressor, and factory wiring harness. However, buyers must beware of hidden mechanical damage, cracked supercharger snouts, bent accessory brackets, and locked OEM computers requiring expensive aftermarket flashing.
Cooling and thermal management represent one of the greatest engineering hurdles when installing a Hellcat motor. The 6.2-liter supercharged HEMI generates immense heat under full boost. To keep intake air temperatures low and prevent the PCM from pulling timing, builders must install dual independent cooling circuits: a heavy-duty primary aluminum radiator for the engine block, and a dedicated low-temperature auxiliary radiator paired with a high-flow electric water pump circulating coolant through the supercharger intercooler bricks.
Drivetrain reinforcement is mandatory when dropping 700 to 800 horsepower into any vehicle. Factory rear differentials, stock driveshafts, and standard passenger-car transmissions will shred instantly under the Hellcat's 650+ lb-ft of low-end torque. Builders typically pair Hellcat swaps with heavy-duty ZF-derived 8HP90 eight-speed automatic transmissions or Tremec Magnum six-speed manuals, custom carbon fiber or 3.5-inch aluminum driveshafts, and bulletproof Ford 9-inch or Strange 60 rear axle assemblies.
How to Plan and Budget a Hellcat Engine Swap
Follow these essential steps to source a Hellcat motor, evaluate transmission pairings, and budget your swap.
Choose Crate Engine Model or Salvage Take-Out
Select a brand-new Mopar Hellcrate (717 hp / $17,000) for zero-mile reliability, or source a low-mileage salvage pullout ($11,000-$14,000).
Order Mopar Direct Connection Engine Control Kit
Procure the unlocked Mopar PCM kit with calibrated sensors and gas pedal to run the engine without immobilizer or CAN-bus issues.
Select Heavy-Duty Transmission and Driveshaft
Pair the motor with a built ZF 8HP90 8-speed automatic or Tremec Magnum manual and order a custom 1350-series U-joint driveshaft.
Design Dual-Circuit Engine and Intercooler Cooling
Install a high-capacity aluminum engine radiator and an independent front-mount heat exchanger with a Bosch supercharger water pump.
Upgrade Fuel Delivery for 700+ Horsepower
Install a high-flow in-tank fuel pump setup delivering at least 450 liters per hour at 58 PSI with PTFE-lined braided fuel lines.
