Your engine. Your next step.
Plan your 6.4L HEMI car build
Rebuild your engine
Have the existing engine inspected and the repair scope quoted. Include the diagnosis, intended use and any requested changes.
Request a rebuild quote →Plan installation
Get the engine, supporting repairs and installation itemized for your vehicle. Tell us where it is located if transport is needed.
Request installed repair →Repair the car you have
Provide the VIN, year, engine identification, transmission and drivetrain. Describe the diagnosis and the condition of components you plan to reuse. Tell us about an existing engine swap or changes to the camshaft, induction, exhaust, fuel system or calibration.
Coordinate the engine and the rest of the car
Choose a replacement or rebuild scope first, then decide whether to include performance work. Review fuel delivery, cooling, controls and transmission needs for a changed combination. The Challenger/Charger package page provides the existing scopes and prices for that conversation.
Questions about this engine path
Does the trim name identify the correct engine?
It helps start the inquiry, but we still need the VIN and actual engine identification. Prior swaps and modifications can change the combination from the original vehicle specification.
Can I combine engine work with an upgrade package?
Ask for one written project scope that identifies the engine work, vehicle package, supporting repairs and tuning. The shop will confirm any overlap so you understand what is included.
Need help choosing? Call 903-262-9502 with your vehicle details. Review matching-core requirements and the product-specific warranty before ordering.

Confirm the assembly, core/exchange terms, freight or installation, schedule and written warranty.

These frames come from our own HEMI build videos: chamber work, the rotating assembly and the engine coming together. Tell us about your Dodge, Ram, Chrysler or Jeep to find the right starting point.

Questions before ordering
Does a catalog match confirm fitment?
No. Matching names or displacement only narrow the search. Big 3 needs the vehicle and engine identifiers to confirm the supplier listing, configuration and any required supporting work.
What is included in the displayed price?
The card displays the catalog product price. Open that same product for its details. Check whether the selected offer includes a refundable core deposit. Confirm any other core/exchange terms, freight, tax, installation and order-specific charges in your quote.
What warranty applies?
Use the selected product's written warranty and confirmed invoice terms. Stock replacements, customer-core rebuilds and performance packages may have different parts and labor coverage. A guide does not expand that coverage.
What if my engine is not listed here?
Product-name search can miss assemblies listed under an engine code or supplier number. Send your VIN and engine details for help; an empty search is not a statement that your engine cannot be supplied.
