Q: Does this crate engine come with everything needed to run?

A: The Mopar 345 Crate HEMI V8 Engine 5.7L Eagle Gen III includes the complete engine assembly, water pump, and either a flexplate or flywheel/clutch assembly. However, it does not include accessories like the alternator, power steering pump, intake manifold usually (unless specified by Mopar), or the engine management system (ECU/PCM) required for operation. These components must be sourced separately to complete your build.

Q: Is this engine suitable for daily driving or just performance applications?

A: This brand-new 5.7L HEMI is designed for both! While it offers significant performance capabilities for enthusiasts, its Mopar factory build quality also makes it a reliable choice for daily driving in appropriate vehicle applications.

Q: What kind of fuel does the 5.7L HEMI require?

A: The 5.7L Eagle Gen III HEMI typically operates efficiently on 89 octane (mid-grade) gasoline, and can use 87 octane (regular) with slight performance differences. For optimal performance and to utilize its full potential, many enthusiasts choose 91 or 93 octane premium fuel, especially if custom tuning is applied. Always refer to Mopar’s specifications and your ECU’s requirements.

Q: What is the warranty on this Mopar crate engine?

A: As a new Mopar part, the Mopar 345 Crate HEMI V8 Engine 5.7L Eagle Gen III is backed by a manufacturer’s warranty. The exact terms and conditions of the Mopar warranty will be provided with your purchase. Spoon Parts USA stands by the quality of the products we sell and will assist you with any warranty claims.

Q: Can Spoon Parts USA help with finding additional parts for my HEMI swap?

A: Absolutely! While our primary focus is on the core drivetrain components, our team can provide guidance on common supporting parts needed for a HEMI swap, such as wiring harnesses, ECUs, and accessory drives.
