The second-generation Camaro Z/28, which made its debut in 1970, is also the best. Not only did this version of the automaker’s most famous muscle car feature an elongated, fastback design, it also packed a new high-performance 350-cubic-inch LT1 V-8, a ground-up rebuild of the Corvette mill of the time. The engine may not have been the biggest available for that iteration of the Camaro, but it was still potent enough to generate 360 hp and 380 ft lbs of torque. That was enough to push the car from zero to 60 mph in 5.8 seconds and to a top speed in the neighborhood of 135 mph.
