In the early 1950s, Chevy and GMC pickups were different in name only. GMCs were Chevy pickups sold in towns without a Chevy dealer. In the 60s, GMC was still the same basic truck as Chevy, but with a significantly more powerful standard engine. The base engine in the Chevy was a 235 c.i. straight six good for 135 horsepower and 216 pound-feet of torque. The GMC however came standard with a V6 of 305 c.i. (bigger than many V8s) producing 150 horsepower and 266 pound-feet of torque.
