'67-'68 390

Car Life called it the "Super Double Deluxeburger Mustang" because Ford decided to add the 390 big-block to the Mustang's engine lineup. With 320 hp and 427 lb-ft of torque, the pony-sized Mustang finally had some beef to compete against big-block GTOs and Barracudas, not to mention the new 396 Camaro. In stock form, the 390 Mustang was a low-to-mid-15-second performer, as evidenced by most of the road tests. Car & Driver reported a 14.8-second e.t. and even complained that the car was not in optimum tune, but failed to provide the transmission type or how they managed to obtain a quicker time than anyone else. Hi-Performance Cars magazine, however, explained that it took a set of slicks and traction bars to register their 14.95-second e.t., stating, "Normally, the 390 engine cannot be considered hot by today's standards. However, when packed into a light Mustang, you have a pretty impressive machine."
