On this episode of HOT ROD Unlimited, David Freiburger meets up with Pro Touring legend Mark Stielow to compare old and new Camaros head to head. Mark Stielow is a GM engineer with a long history of building vintage, street-worthy Camaros with amazing handling prowess. His latest is the Red Devil, a '69 model powered by a 427ci, supercharged LS9 that tops 750 hp and 800 lb-ft. It runs a six-speed trans and complete suspension from Detroit Speed, and has won a number of shootouts with similarly built Pro Touring cars. But can his modified muscle car outrun the technology of the Magnetic Ride suspension on the new, 580hp, 2012 Camaro ZL1?
