Repairing, customizing and restoring a wide variety of cars and light trucks are what keep the two guys on this series busy. Hosts Kevin Byrd and Willie B also perform product demonstrations and visit well-known shops in the auto performance and engineering industry.
The guys do a complete deconstruction of the new Scorpion diesel engine, showing how the new technology and block design completely revolutionized the 6.7L engine.
Kevin and Willie get a problematic Trailblazer up and running again, and kick-start a performance build project on a fifth-generation Chevrolet Camaro.
Matt helps a friend prepare his Dodge Ram 2500 Longhorn for its next camping and hunting trip; as a trade out, Matt gets a little party time in the trailer.
Willie B. and Kevin go under the hood of the new Mustang EcoBoost 4-cylinder to add some performance upgrades; progress on an old pickup project continues with rust repair and new body panels.
With a powerful Dodge Challenger in the shop for maintenance and performance upgrades, Kevin and Willie can't resist adding on a new exhaust for the owner as well.
When Willie and Kevin find a 1953 M37 sitting in a friend's garage next to a Cummins 4BT and all the parts needed for an engine swap, they volunteer to provide the labor.
