David Freiburger released a walk-around video with a lot of interesting details on the Muscle Truck. The truck is a 1974 Chevy C-10 stepside that was originally built when David was working at Car Junkie TV. The engine is a 5.7 L LS6 V8 with a Crane camshaft, Crane roller rockers and MSD Atomic EFI. Behind it sits a Turbo 400 three-speed automatic with a Gear Vendors overdrive connected to a 1978 Ford F-100 rear end with 3.50 gears.
Below are all the previous Roadkill and Hot Rod Garage episodes featuring the Muscle Truck in chronological order.
