More Power. Increase the horsepower and torque output of your push rod 5.0L engine with a Top End Engine Kit from AmericanMuscle that includes Ford Racing Turbo-Swirl GT40X Aluminum Heads. This Top End Engine Kit will greatly improve airflow over the original stock design allowing you to bolt-on over 65 more rear wheel horsepower.

Kit Includes. This Top End Engine Kit includes Ford Racing Turbo-Swirl GT40X Aluminum Heads, Comp Cams Xtreme Energy XE264HR Stage I Camshaft, Typhoon Intake Manifold, Aluminum Valve Covers, Magnum Double Roller Timing Chain Set, ARP High Performance Series Head Bolt Kit, and a Ford Racing Engine Gasket Kit.

GT40X Aluminum Heads. Made from high quality 356-T6 aluminum castings, these Ford Racing GT-40X heads have an intake port volume of 178cc allowing for an intake flow of approximately 240 cfm at .550" lift (at 28" of H20) and an exhaust port volume of 62cc allowing for an exhaust flow of approximately 170 cfm at .500" lift (at 28" of H20). Machined for 1.94" Intake and 1.54" exhaust valve diameters.

Xtreme Energy Stage I Camshaft. This Comp Cams Xtreme Energy Hydraulic roller lifter cam is a good replacement upgrade for the High Output (HO) 5.0 that was featured in the later Fox Body Mustangs for mild street performance gains. Perfect for bolt on modifications to make good overall power with a smooth idle without sacrificing daily drive-ability.

Typhoon Intake Manifold. Completed in a natural satin finish this aluminum Professional Products Typhoon Intake Manifold will allow your Pony to breath much easier with no loss of low end torque. A 70mm Throttle Body is recommended for optimum performance of your 5.0 Mustang.

Application. This Top End Engine Kit is designed for use on the 1987 to 1993 Mustangs equipped with the iconic 5.0L V8 engine, including the LX 5.0, GT and SVT Cobra models.
