The challenge of resurrecting some of the most wrecked muscle cars on the face of the earth.

With the 1970 Plum Crazy Challenger nearing completion, works shifts to the 1970 Tribute Superbird; Mark and Cousin Dougie build out a 340 engine; Will assists George with metal work to help him stay on schedule.

The 1970 Plum Crazy Challenger that has been featured since the show's beginning is finally finished; the vehicle is shown off before it is shipped to its new owner.

Work ramps up on the 1970 Tribute Superbird; Mark begins work on a new project, a 1968 Plymouth GTX owned by "Overhaulin'" host Chris Jacobs.

Stress levels rise in the shop when Mark learns that the owner of Tony's Mopar Parts will be arriving to check on the progress of his 1970 Dodge Challenger; Mark distracts Tony while the team hustles to begin the vehicle's restoration.
