Hellcat Engine for Sale: Your Ultimate Guide to Buying the Legendary Powerhouse

If you’re a performance car enthusiast, you’ve likely heard the roar of the Hellcat engine—a monstrous V8 powerhouse that has redefined American muscle. Whether you’re looking to buy a Hellcat engine for your car project, restore a Challenger or Charger, or simply want to experience the raw power it delivers, this guide will walk you through everything you need to know about finding a Hellcat engine for sale.

What Is a Hellcat Engine?

The Hellcat engine refers to the supercharged 6.2L HEMI V8 developed by Dodge (Stellantis, formerly FCA) and introduced in 2015 with the Dodge Challenger SRT Hellcat. It quickly became famous for delivering over 700 horsepower right from the factory, a level of performance that was previously unheard of at its price point.

Key Highlights:

• Supercharged 6.2-liter V8

• Horsepower: 707 to 807 HP (depending on model/year)

• Torque: 650–717 lb-ft

• Featured in: Challenger SRT Hellcat, Charger SRT Hellcat, Jeep Trackhawk, RAM TRX, and Dodge Durango SRT Hellcat

This engine is part of the broader Hemi family, but stands out due to its supercharger, forged internals, and performance upgrades.

Hellcat Engine Swap: What You Need to Know

Planning a Hellcat engine swap? Here’s what to consider:

Compatibility

• Requires reinforced transmission, rear differential, and upgraded cooling.

Parts Required:

• ECU & wiring harness

• Radiator/cooling system

Red Flags to Watch for When Buying a Hellcat Engine

1. No VIN provided – Always verify origin to ensure it’s not stolen.

2. No compression test or leak-down report – Vital to know engine health.

3. No supercharger included – Many listings exclude this key part.

4. No wiring harness or ECU – You’ll spend thousands sourcing them separately.

5. Price seems too low – Be skeptical of deals under $10,000.

✅ Pro Tip: Ask for a video of the engine running if it’s still in the donor vehicle.
