The 1969 Shelby GT500 Sportsroof represents the evolution from both Shelby and Ford. By 1969, the production Ford Mustang was redesigned as a larger and more luxurious model. Many special models made available by Ford themselves which directly competed with previous Shelby upgrades. More than ever before, the 1969 Shelby Mustang featured comfort and convenience. The car was powered by Ford’s Super Cobra Jet 428 V8 engine, geared through a C6 automatic transmission and a traction-Loc limited slip rear axle. The drag pack included this differential, an engine oil cooler and 427-type connecting rods.
