I have a 2015 Challenger that I bought from an auction with basically no history. It runs strong, but a buddy looked under the hood and asked if the engine was original, and honestly I could not answer him. Before I tear into casting numbers, I would rather start from paper. Can a Dodge VIN actually show which engine the car was born with? And is that information specific enough to distinguish between the different V8s offered that year, or does it just say eight cylinders and call it a day?

The eighth character of your VIN is the engine code, and for 2015 it distinguishes the V6 from the 5.7 from the 6.4 and up. Decode it and you will know exactly which engine the factory installed. Then compare displacement with what is physically in the bay.

Paper first is the right instinct. VIN gives you the born-with engine, the equipment listing confirms it, and only then bother with casting numbers if something disagrees.

Eighth character says 5.7 and everything in the bay agrees with it. Original engine confirmed, mystery solved without pulling a single part, and my buddy owes me lunch. Appreciate it, both of you.
