First came the 428 cubic-inch Ford Mustang Cobra Jet for 1968, then the 429 Super Cobra Jet for ’69. Ford recently revived the Cobra Jet moniker for a 40th anniversary, quarter-mile attacking model based on the 2008 Mustang. Building on that successful program, Ford Racing is employing the Cobra Jet moniker again for the new, heavily revised 2010 Mustang. That’s not 429 cubic inches under the hood, but with a Whipple 4.0-liter supercharger fitted atop the 5.4-liter V-8, the engine makes a reported 425 horsepower in “base” Cobra Jet form, with applications up to 475 hp.
Other Cobra Jet features include fully adjustable front and rear shocks, custom Weld racing wheels, a competition shifter and full instrumentation, competition harnesses with a full cage and a 4.29:1 final drive. Set up for Super Stock B and Super Stock B Automatic, it comes with mechanical brakes, manual steering and sans sideview mirrors.
To mark the car's debut at the 2009 SEMA show, Ford built the special one-off "SEMA Special" silver Cobra Jet you see pictured here, featuring a charcoal graphics package with Super Cobra Jet markings.
Ford SVT claims the Cobra Jet will grab a quarter-mile in the 8-1/2-second range. Ford plans to build 50 per year (all 50 for this year are already spoken for) and sell them through them through Ford dealerships. The Mustang Cobra Jet stickers for $77,800 and can be optioned up to $93,800.
