During the latter portion of the 1960s, few production engines were as potent as the 428 cubic-inch Cobra Jet V8. Ford settled upon the beastly big block as a direct response to other large displacement engines of the day, offered by Mopar and Chevrolet. This engine was built upon the basic design of Ford’s 427CI Police Interceptor V8, with the addition of a more robust crankshaft, heavy-duty connecting rods, and a larger 735 cfm Holley carburetor.
All things considered, the 428CI Cobra Jet’s output was officially rated at 335 horsepower. However, it is well known that these numbers were greatly understated. In fact, the Cobra Jet’s true output is said to have easily exceeded the 400 horsepower mark.
This 1970 Ford Mustang boasts a Bright Blue Metallic exterior over white vinyl upholstery and is propelled by a 428ci Cobra Jet Ram Air V8 paired with a four-speed manual transmission and 3.50:1 differential. The factory rating for the engine was 335 horsepower and 440 lb-ft of torque.
