Every Car Featuring Ford’s Powerful 428 Cobra Jet Engine
The Ford 428 Cobra Jet engine held a transformative role in the muscle car landscape of the late 1960s. This powerful engine emerged from the competitive pressures faced by Ford as General Motors and Chrysler introduced their range of big-block V8s. A collaboration spearheaded by Bob Tasca, a Ford dealer in Rhode Island, led to the enhancement of the existing 428 cubic-inch engine into the iconic 428 Cobra Jet.
The Birth of the 428 Cobra Jet
In 1968, the 428 Cobra Jet engine was created by combining a Police Interceptor block and cylinder heads from the 427, augmented with a robust performance camshaft. This configuration was paired with a Holley 735 CFM four-barrel carburetor, yielding an official output of 335 horsepower and 440 pound-feet of torque. However, automotive experts speculated that the actual horsepower was likely closer to 400.
With its introduction, Ford decided to incorporate the 428 Cobra Jet across various models, revolutionizing the racing and street car market.
