John Szwarc built his 1969 Chevy C10 to be different. In the truck’s bed sits a 454 ci Chevy V8 with a Comp Cams Big Mutha’ Thumpr camshaft. The truck’s unique drivetrain features a TH350 three-speed automatic transmission connected to a Ace Champion V-drive. The V-drive sends power forward to a GM 12-bolt rear end turned backwards. To compensate for the change in weight, John installed air bags in front and helper leaf springs in back.
