This is what 700 Horsepower on pump gas looks like. A Cobra Automotive exclusive installation, this setup is for the performance enthusiast who wants the ultimate in stealth performance. These kits are made to fit under the hood and are available for most replica Cobras, Shelby Mustangs and even original Cobras. Our first one was unleashed on the streets of America in 1985 and, over the years, continuous development has refined the installation as well as its performance. Pictured here is a 427 Medium Riser in a 1967 Shelby GT500 that made 705 HP on the dyno (thru the mufflers) on pump gas. Imagine all that hardware under the hood of your car, with docile street manners. Contact us at (203) 284-3863 with your application. Custom-built setups can be designed for other applications as well.
