Junkyard Empire

When Andy tries to convert an old Dodge pickup into a vintage power wagon, his dad hits the roof. It's up to Chris and Jeff to turn this rust bucket into gold. Then Andy buys a German military truck for a crazy advertising scheme.

Andy and Bobby treat their employees as members of the family. So when Tim's son wants a bigger truck, they happily hook him up. But it'll take a lot to turn a wrecked K-9 explosives police wagon into a camo-wrapped hunting truck.

Bobby spots a rusty British cab at the junkyard and vows to do what he can to save it. Andy thinks he's crazy and decides to make a big investment in a Lamborghini Murcielago to recoup the money he worries Bobby will lose.

It's all hands on deck to get a 2010 Dodge Viper's V10 roaring again. The crew is also fixing up a 1950 fire truck for the local firehouse. Money's tight so Andy gets creative to put Big Red back on the road.

Andy attempts to transplant a modern Ford EcoBoost engine into an '85 Mustang SVO, a car built around an outdated 2.3 liter motor. The guys get started on a tribute to Andy's favorite car from the 70s, the 1970 GTO Judge.

When Andy scores the only wire harness that can marry his SVO Mustang to a new EcoBoost engine, he pressures Blair to bring it to life. George cuts an F350 in half to create the first single-cab, short-bed diesel pickup truck.

A friend asks Andy to help restore his dad's 1964 Mustang, but the project is more than Andy bargained for. Andy's girlfriend wants him to sell her under-powered Jeep, but after he fixes it up, she throws a wrench in his plans.

Andy needs everyone's help to transplant a Dodge Hellcat engine into his classic Plymouth Barracuda. But even his best guys can't promise it will work. Bobby tries to salvage two beat-up ATVs without losing any money.

Andy's new-school-meets-old Barracuda build keeps hitting setbacks. Dave can't catch a break and morale hits a new low. Then, Tommy's bringing some retro-cool to a junked helicopter, and a '71 Chevy Blazer gets a big power boost.

Andy wants another shot at the world speed record for tow trucks in his Racing Wrecker, and Bobby wants in with a 1979 Zephyr with a new engine. Neither knows that a third racer will show up with a sleeper that wakes everyone up.

Andy and Bobby live by the motto that cars create memories, and they're about to restore two classics. One is a Jeep Wrangler that's an American icon; the other is a 1986 Monte Carlo -- once known as "The Heartbeat of America."

When Andy wants to squeeze a Hemi into a Jeep Wrangler for a power boost, there's no end to what could go wrong. Jeff's reviving an '86 RX-7 with a Corvette LT1 motor, and Tim's rehabbing a Boston Whaler for a high-seas adventure.
