2004 Ford Mustang SVT Cobra — Complete Supercharged Engine, Tremec T56 6-Speed Transmission & Gas Tank Assembly
This is as complete and authentic as it gets — a 2004 Ford Mustang SVT Cobra supercharged drivetrain packagepulled from a 99% stock, well-preserved Cobra with only 56,000 original miles. This listing includes the complete supercharged engine assembly from pan to blower, a Tremec T56 6-speed manual transmission, and the gas tank assembly — one of the most comprehensive and desirable SVT Cobra packages you’ll find on the market today.
The 2003–2004 SVT Cobra is legendary for good reason. Ford’s hand-built 4.6L DOHC supercharged V8 — topped by the iconic Eaton supercharger — produced a factory-rated 390 horsepower and 390 lb-ft of torque, numbers that were widely known to be conservative. These engines routinely outperformed their ratings and became the foundation for some of the most respected Mustang builds ever put together. The 2004 model year is especially sought after for its upgraded DB9 thread heads, which offer improved strength and are highly regarded among builders and enthusiasts.
This engine was pulled from a car that was as close to factory spec as possible — the only modifications were a cat-back exhaust and a short throw shifter. That means the engine, blower, and drivetrain spent their entire life in a stock, responsibly driven environment. The result is a low-mileage, unmolested supercharged assembly that is ready to be the centerpiece of an elite Mustang restoration or performance build.
The engine comes complete with most of the Eaton supercharger accessories already in place. To complete the installation, you will need a heat exchanger, brackets, pumps, and lines — standard items for any serious builder working with this platform.
