Limited 428 Cobra Jet Mustang production began with a run of 50 (enough to qualify for NHRA stock racing classes) non-GT fastbacks (body style 63A) that were scheduled for assembly at the Dearborn assembly plant on December 30, 1967. The VINs were serialized consecutively starting with 8F02R135007 and ending with 8F02R135056. All were painted Wimbledon White and equipped with a black vinyl interior (code 2A), heavy duty 4-speed manual transmission (code 5), manual drum brakes, and (code 7 (3.25:1) door tag code notwithstanding) a 3.89:1 rear axle ratio.
On January 28, 1968 Hubert Platt introduced the 428 Cobra Jet Mustang to the racing world during the AHRA Winter Nationals held at Lions Drag Strip near Los Angeles. He drove one car in C/Stock and red-lighted a 12.62 run in the first round of Top Stock.

Have you ever wondered just how fast your car might really be in the quarter mile? Guess no more -- take it to your local drag strip and find out! Once you know for sure I'll gladly post your results and a copy of your time slip, and we'll confirm how our cars really measure up. Results for both 1/8 mile runs and 1/4 mile runs are both appreciated.
