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

Mark Hill's '70 Superbird is torn down; finishing touches are put on Chris Driscoll's '70 AAR 'Cuda; Daren confronts Mark about stolen car parts; Mark gets a rematch on the racetrack.

Holly asks permission to work on vehicles; the crew receives a gift from Mark Cain of Bad Boy Blasters; the torn-down '70 Barracuda is sent to the dipper; an actor surprises Mark.

The hood decal is installed on the '70 Challenger; Josh and Holly disassemble the Barracuda's suspension; the team works on the Challenger's 440 engine and sunroof.

The team hurries to finish the '69 Dodge Daytona; a leadership dispute is settled in an old-fashioned manner; Daren strikes back when Mark won't allow him to sign for deliveries.
