Book II · The Coiled Entry 11 of 55
Ford 428 Cobra Jet
Not a car. An engine that became a promise.
The Cobra Jet is the only entry in this book that has no bodywork of its own. It is a cylinder head philosophy that Ford has been re-issuing for nearly sixty years.

Sigil generated from the entry's own name. Every coil, hue and scale in this plate is a function of the string “ford-cobra-jet”, and of nothing else.
In 1967 a Ford dealer in Rhode Island named Bob Tasca got tired of losing to Chryslers and built his own big-block combination, then agitated publicly until Ford paid attention. The result was the 428 Cobra Jet: a 428 block with larger-port heads derived from the 427, a big intake, and a factory rating that was widely understood to be a work of fiction filed for insurance purposes.
It appeared in Mustangs in 1968, went straight to the drag strip, and won. The Super Cobra Jet followed with a stronger bottom end for cars ordered with the drag-oriented axle ratios.
What is remarkable is the persistence. Ford has revived the Cobra Jet name repeatedly — most recently on limited-run, factory-built drag Mustangs that are not road legal and are sold specifically to people who intend to spend their weekends going in a straight line for a quarter of a mile at a time.
A snake that strikes covers a very short distance extremely quickly and then stops. It does not pursue. It does not corner. It commits everything to a single line and then reassesses. The Cobra Jet is the only serpent in this book whose behaviour maps onto the animal with total precision, and it is not a coincidence that it is the one named after the strike rather than the animal.
A quarter of a mile is roughly the distance a snake believes in.
Questions people actually ask
What is a Ford Cobra Jet?
Originally a high-performance version of Ford’s 428 cubic inch big-block V8, introduced in 1968 with cylinder heads derived from the 427. The name has since been revived for limited-production factory drag racing Mustangs.
