Carbureted Small Block Ford Entry-Level Systems

Part Numbers and Prices listed below.

Add up to 75% more horsepower to your Small Block Ford at a low cost with a Paxton Entry Level Universal Supercharger Kit, featuring the Paxton PowerHat™ Carburetor Bonnet Assembly with diffusion technology.

• Designed for 1964-1968 small block Ford applications equipped with carbureted 260-302ci engines.

• The kit allows retention of power steering and the alternator (generators must be replaced).
• 1967-68 Mustangs may require relocation of the battery
• Horsepower gains (depending on boost levels, engine volumetric efficiency etc.): 30-75%+
• Supplied pulley ratio will produce approximately 6-8 psi at 5500 rpm on a mildly modified 289” engine
• Installation time: 4-10 hours depending on application
• CARB E.O. numbers do not apply to this kit
• The supplied supercharger discharge tube is intended to fit a wide range of manifold heights; however, applications equipped with “high-rise” intake manifolds may require minor adjustment/trimming for optimum fit.
