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? We head to GingerMan Raceway in South Haven, Michigan to find out.
