The "performance" of pony cars became a major arena of competition, both for sales and manufacturer prestige. As the horsepower war escalated, the Ford Mustang platform and engine bay were redesigned to accommodate larger engine blocks. Late in the 1968 model year, Ford introduced the 428 cu in (7.0 L) Cobra Jet FE engine in a small group of Mustang GTs and the 1968 Shelby GT500KR, its largest and most potent "performance" engine. For the 1969 model year, Ford produced an overall "performance package", which was available with two smaller V8s - the 351 cu in (5.8 L) Windsor (standard) and 390 cu in (6.4 L) FE, and topped by the Cobra Jet. It included some additional handling upgrades and heavy appearance enhancements and was dubbed the "Mach 1". Other engine options became available from 1970 through 1973.
Built to be the quickest factory drag racing car in 1968, the Cobra Jet Mustang was conceived by Bob Tasca of Tasca Ford and pushed into production at the urging of customers. The 1968 Ford Mustang 428 CJ obliterated everything in the Super Stock class at the 1968 NHRA Winter Nationals.
This is believed to be the highest scoring, nationally judged 1968-½ Cobra Jet Mustang. It is 1-of-51 "drag pack" cars and is rated at 0-60 mph in 5.4 seconds.

For the record, the overwhelming majority of '68-or '68½, if you prefer-CJ Mustangs were built in Dearborn. Of the 1,299 non-Shelby, first-year Cobra Jets, only 171 came together in San Jose. The northeast assembly plant at Metuchen, New Jersey, built none.
