The 340-cubic-inch V8 engine that came stock with this Mopar makes 275 horsepower and 340 lb-ft of torque,

but it doesn't have a 440 Six Pack or a 426 Hemi V8. It's interesting to note that this car's engine isn't the

original. Instead, it's a Chrysler 340 V8 that's said to have come from a 1970 Plymouth Cuda. In spite of this, Ryan and Seth

that the casting code on the transmission matches, which shows that the engine is the real deal. The owner of the car, Mitch, has the original, matching-numbers 340 V8 sitting in Greg's garage, which is even better.

Buy something. For those who choose to spend a lot of time and money on a full Mopar fix, Mitch will get a

truly valuable Challenger. The frame and both engines, on the other hand, probably need to be rebuilt from scratch.
