Is the Dodge Challenger 5.7 Hemi engine OEM?
Is the Dodge Challenger 5.7 Hemi engine OEM? One would think Dodge would have slipped in a few performance internals into them at the Mexican factory. Yet this is why this engine responds so well to performance add on's. After all it's a truck engine. BUT modifying the 5.7 voids the OEM warranty. So don't make the error of not buying the 392 SRT engine car for a mere $10,000 more. Is the 5.7 Hemi an across line up engine? Few know that the 5.7 Hemi is a across the line up engine. Meaning no matter which Mopar you buy...
