Hot Rod Magazine teamed up with Ligenfelter Engineering to break the 200 mph barrier in the new Chevrolet Camaro ZL1. Ligenfelter put a new cam, CNC ported heads, cold air intake, fuel system and engine management into the factory supercharged Camaro to bump the power to 720 hp at 6500 rpm and 650 foot-pounds of torque at 4650 rpm. The car was the first ZL1 to run a 10 second quarter mile pass and they wanted to see if it could match the upcoming Shelby Mustang’s claimed 200 mph top speed
