Ford Mustang 428 Cobra Jet Convertible Recreation

With the sagging performance of the 390-powered Mustang on both the drag-strip and the showroom floor in late 1967, Ford developed the 428 Cobra Jet at the suggestion of Ford dealer Bob Tasca and the editor of Hot Rod magazine. Released on April 1, 1968, the reliable, high-torque Cobra Jet was a masterful combination of high-performance components already within Ford’s parts bin. Among them were a pair of 427 low-riser heads and a 427 intake. The package also included a 735 cfm Holley four-barrel carburetor and 10.5:1 compression. Heavy-duty underpinnings included staggered rear shocks and reinforced front shock towers, among other modifications.

Capable of low 14-second quarter-mile times in stock trim and mid-11s in racing tune, Cobra Jet Mustangs quickly established a fearsome reputation. In their racing debut, Ford launched a six-car Cobra Jet attack at the 1968 NHRA Winternationals. Ford-sponsored drivers included such legends as Gas Ronda, Jerry Harvey, Hubert Platt, Don Nicholson and Al Joniec. All six cars were race-prepped by Holman-Moody-Stroppe in Long Beach, California.

A number of classes were contested, including C/Stock Automatic (C/SA), Super Stock E (SS/E), and Super Stock E Automatic (SS/EA). When the smoke cleared, four of the six Cobra Jet Mustangs reached the final rounds of their respective classes. Incredibly, the all-CJ SS/E final round found Joniec and Platt at the starting line, with Joniec taking the class victory with a 12.49-second ET, going on to win Super Stock Eliminator over Chrysler stalwart Dave Wren.

This car was auctioned off by RM Auctions in November of 2010 at the Robson Estate, Gainesville, Georgia.
