1968 428 Cobra Jet

With the launch of the Mustang 428 Cobra Jet on April 1, 1968, many enthusiasts were probably waiting for the punch line to the joke. But it wasn’t a joke. Ford built a Mustang with Ram Air induction, naming the result the 428 Cobra Jet. Touted as having 335 horsepower, many thought this number was purposely underestimated to avoid higher insurance premiums. Reportedly, actual output was closer to 400 hp. Visually, the 428 Cobra Jet’s hood scoop and black striping gave it away to passersby. And those who couldn’t row their own gears via the standard four-speed manual could opt for a three-speed automatic transmission.
