John Hennessey is not known for leaving anything in stock form. But in order to know how effective his modifications are, it's necessary to know how fast each car is before the transformation. In a new YouTube video uploaded by Hennessey Performance, we have a rare opportunity to see a roll race between a new 2017 Camaro ZL1 and a Corvette Z06. In a rare move by Chevrolet, both cars are rated at 650 hp and 650 lb-ft of torque. The supercharged LT4 V8 is a 6.2 engine with direct injection and an all-aluminum construction. Camaro has a traditional layout of front-engine with the transmission close behind it, but the Corvette has the transmission mounted out back, connected by a torque tube. Since this is the last time both cars will be in factory form, why not see what they are capable of?

Depending on options, the Camaro can be anywhere from 300 to 500 pounds heavier than its fiberglass cousin. To simulate a true street race, both cars lined up for a roll race at Hennessey's Lonestar Motorsports Park. Both cars are manual transmission -- the seven-speed Z06 vs a six-speed ZL1.
