It’s make or break time for Aaron’s crazy Scat Pack Challenger transplant scheme, as Richard’s potential buyer will only be in town for one day, and if the build isn’t finished by then, Richard could potentially be saddled with two worthless cars.

Richard’s big gamble of bringing seven cars to this year’s Barrett-Jackson auction in Scottsdale, Arizona, is put to the test, as Aaron makes a pit stop in Las Vegas to oversee team Gas Monkey’s NHRA Top Fuel dragster.

Richard buys a ’78 Cutlass so Aaron can build Gas Monkey’s first ever lowrider, he only to discover that Aaron’s plan to create custom hydraulics is something he’s never attempted before.

As Richard heads to Houston to check out Gas Monkey’s top fuel NHRA dragster do some racing, the Monkeys need to do some racing of their own to finish a custom lowrider paint job on the ’78 Cutlass in time for the car’s debut.

With less than four days left in the season, the fleet races to claim the title of top-earning boat, but with two captains sidelined, it’s anyone’s game.
