Chrysler 6.4L 392 HEMI® V8 Vehicles in Western PA

For drivers in Western Pennsylvania who want the absolute maximum power available in a factory Chrysler sedan, there is only one option: the 6.4L 392 HEMI® V8. While the 5.7L HEMI is powerful, the 6.4L is a different tier of performance entirely.

This engine was absent from the US Chrysler 300 lineup for years but made a brief, powerful return for the 2023 Chrysler 300C Final Edition. Because production was strictly limited (only 2,000 units were made for the US), seeing one on the streets of Butler or Cranberry Township is a rare event. If we have one in our inventory, it represents the pinnacle of American sedan performance.

The "392" refers to the engine's displacement in cubic inches, a historic number for Chrysler performance. This naturally aspirated engine delivers massive power without the need for turbochargers, providing instant throttle response perfect for the hills of Mercer County.

Expert Insight:

Active Exhaust System

How does a luxury sedan sound like a muscle car? The 2023 Chrysler 300C 6.4L features a standard Active Exhaust System.

The Tech: An electronically controlled valve system automatically opens the exhaust pipes when you press the gas pedal firmly.

The Result: At cruising speeds on Route 18, the car is quiet and refined. But when you accelerate to merge onto I-80, the valves open to unleash a deep, aggressive V8 growl that lets everyone know this isn't a standard sedan.

Available Models with the 6.4L HEMI V8

Unlike other engines that appear across multiple trims, the 6.4L HEMI is exclusive to a single, specific model year and trim level in the modern era.

2023 Chrysler 300C (Final Edition):

This is the only version of the 300 sold in the US between 2015 and 2023 to feature the 6.4L engine. It comes standard with red 4-piston Brembo® brakes and Active Damping Suspension to handle the extra power.

Note: If you see a listing for a "Chrysler 300 SRT" from 2016-2022, be cautious. That model was not sold in the United States. The 2023 300C is the authentic US-market performance flagship.

Owner’s Corner: Maintenance Mike Kelly Pro-Tips

The 6.4L 392 HEMI is a high-performance machine that requires specific care. Follow these rules from the Mike Kelly Chrysler Dodge Jeep Ram Service Center:

Oil is Non-Negotiable: This engine requires 0W-40 Full Synthetic Oil. Do not use the 5W-20 found in the 5.7L engine. The 0W-40 formula is designed to handle the higher heat and stress of the 485-horsepower engine.
Premium Fuel Only: To get the rated horsepower and prevent engine knock, you should strictly use 91 octane or higher premium fuel.
Brake Maintenance: The Brembo® brakes offer incredible stopping power but generate more dust than standard brakes. We recommend regular wheel cleaning to protect the finish of the 20-inch forged wheels.
