Today we’re going to go back to the classic rivalry that needs no introduction: Camaro versus Mustang. And we’re going to examine it from the proving ground where the two vehicles are so often compared: the drag strip. And we’re going to specify it with who has the fastest “H-Pattern” muscle car out there. In other words: Who has the quickest, fastest muscle car in the world with a stick shift. Well, at the moment that title for the quickest H-pattern car in the world goes to Johnathan Atkins and his 1997 “Grubb Worm” Chevy Camaro. The fourth generation F-body Camaro puts out an estimated 2,000 horsepower and ran a 6.61-second quarter-mile time running at 216 mph earlier this month. It’s a record that was previously held by a Ford Mustang.
