Amid all of the incredible Mustangs and hot rods on the Power Tour, there was one car today that totally stopped us in our tracks, and we nearly missed it. What we thought was a nice, lowered, ’70 Mach 1 Mustang with cool wheels was in fact a wolf in sheep’s clothing. Georgia’s Bobby Johnson, who is no stranger to show-winning hot rods, drove out his latest creation (that’s right, he drove it, not trailered it) to the Hoover (Alabama) Metropolitan Stadium and parked it amidst the other participants like it was just an everyday Mustang. But walking around to the open rear hatch (our first clue) revealed a blown 4-valve mod motor and transaxle from a Ford GT mounted behind the rear seats. Huh?

Johnson got the drivetrain (which is stock) from an outfit that parts out wrecked GTs and thought, “Why not?” So he built a complete chassis for the car, with a chromoly roll cage and all aluminum control arms, and dropped the mostly stock ’70 SportsRoof body on top of it. If you look close, you’ll notice that the rear wheelwells were moved back roughly 3 inches—Bobby is around 6-foot 4-inches tall and lengthened the car a little so it was comfortable for him to drive. The dash is from a ’99 Mustang, and there are one-off carbon fiber parts everywhere. Under the hood is the radiator, fuel tank, and water tank for the intercooler. Johnson said it weighs about 3,700 pounds, and with air conditioning and the factory GT drivetrain, “You can drive it anywhere, and I do.” The paint he calls Grabber Orange, but it’s actually a newer Shelby color. The car brings back memories of the Mach 40 ’69 Mustang that was done a few years ago, but the difference is that that car had beautiful but severe body modifications, and Johnson’s car retains the stock ’70 fastback proportions, save for the lengthening job on the quarters. Watch for a full feature in an upcoming issue of Mustang Monthly, and also on Mustang-360.com.

Today’s drive was good, with a 270-mile trip that wound us past Oxford, Mississippi, through Birmingham, Alabama and ended in nearby Hoover at the Hoover Metropolitan Stadium. It’s warm and pretty humid, but the crowds were still huge. Tomorrow we’re on to Gulfport, Mississippi where we’ll stop at Centennial Plaza. Come on out and say hi, won’t you?

Bobby Johnson’s ’70 Mach 1 looks like a nice Pro Touring car with big brakes and fat tires, but it’s much more than that.
The 5.4L Ford GT engine and transaxle sit amidships, behind the front seats, and help to create a roughly 60/40 rear/front weight distribution. Johnson put a smaller pulley on the blower, but other than that it’s as-built from Ford.
Where the engine used to be is now home to the radiator (mounted under the carbon-fiber cover), the fuel tank, and the water tank for the intercooler.
The dash is from a ’99 Mustang.
Bobby Johnson stands proudly by his mid-engine ’70 Mach 1. Yes, he drove it there, and he drove it home.
We didn’t get the owner/builder’s name, but this creation has caused quite a stir on the Power Tour. It’s a fully custom-built body on top of a ¾-ton diesel truck chassis, and has enough interior room to play baseball in. It’s a Long Hauler.
