This old-school sports car needs some new-school power, and Kevin and Willie are up for the challenge. They’ll be pulling out the old side-mounted engine and transaxle in a Dodge Stealth and mocking up a newer inline 3.6L, V6. By the time they’re finished, they’ll have converted this front-wheel Dodge Stealth into a roaring beast.

Willie and Kevin repair a Pontiac Vibe to be given away to Willie’s charity, “Cars for Christmas.” The guys will start by removing the top end to see what kind of shape the head gasket is in, and find out if the engine is repairable, in hopes of getting this Vibe back on the road.

After a friend of the shop got in an accident, Willie and Kevin wanted to help fix their Camaro’s front end. Finding new body panels that are already painted to match the vehicle color will make this fix even easier. The guys also have new headlights and side marker lights to install, plus some new Camaro badging as a final touch.

The guys have the ‘69 GTO back in the shop for the next stage of its frame off restoration, including prepping, priming, and mocking up the body on the updated frame to check the clearance on the suspension and the new drivetrain. Then it’s on to the new, high-dollar motor and TREMEC 5-speed transmission before the body goes back on and the guys get their first look at how – and if – it all fits together.

Kevin and Willie take the handoff from pals Matt and Bruno from Truck U, as they outfit a brand new 2024 Kia Telluride. It's being customized as an overlanding vehicle for Total Energies en route to the 2024 SEMA Show, where the truck will be prominently displayed and given to a sweepstakes winner.

The guys bring in a friend’s numbers matching 69’ GTO Judge for a frame-off restoration.

The owner of this supercharged 2016 Mustang GT goes to car shows on the weekend and needs some help standing out from the pack.

There are too many noises coming from the steering and suspension of this 2006 Mini Cooper S, so Willie and Kevin put in a new tensioner, replace the axles, upgrade the brakes, and answer the age old mystery, “Can two grown adults fit in a Mini Cooper?”

Kevin and Willie bring in a 1981 C3 Corvette that needs an AC repair, along with some rear end noise that needs to be diagnosed, and a headlight winking problem that needs to be fixed.
