You can access elite performance with the 6.4L 392 HEMI V8, which represents the peak of naturally aspirated power. This engine occupies the space between the supercharged models and the standard V8, providing high-output capability that remains manageable for daily street use while remaining dominant on the track.

Whether you are looking for a pre-owned Scat Pack or a brand-new performance vehicle, the "392" designation represents a significant level of engineering authority.

Why Buy a 6.4L HEMI from Us?

You are investing in a high-performance machine that demands specific maintenance protocols. Buying a used 392 from a private seller can be risky, as neglect can lead to premature wear on the camshafts or lifters. It is often impossible to know if a previous owner used the required synthetic oil.

We verify the mechanical health and service history of every performance engine in our stock. Our team at Ed Martin Chrysler Dodge Jeep Ram ensures that you receive a vehicle capable of its full rated performance.

Maintenance Pro-Tips

You can preserve the life of your 6.4L 392 HEMI by following these rules from our service department:

Maintenance Pro-Tips
  • Strict Oil Requirement: You must use 0W-40 Full Synthetic Oil. The high heat and tight tolerances of this engine require this viscosity to protect internal bearings.
  • Warm Up: Always let the oil temperature rise before you attempt hard acceleration, as the valve train requires proper lubrication that cold oil cannot provide.
  • Premium Fuel Only: This motor uses high compression and requires 91 octane fuel or higher to avoid engine knocking and ensure full output.
