DESCRIPTION: The Edelbrock Performer Truck 5.8 manifold is designed for 1988-1995, 5.8 Liter small-block Ford engines equiped with Electronic
Fuel Injection in trucks only; will not fit passenger car applications. The modular design incorporates the latest technology for maximum power gains
in the mid-range where trucks need it most. On our test engine, this manifold made 34 ft./lbs. of torque over a stock intake manifold. It is a stock
replacement, street legal manifold designed to function with all original equipment fuel injectors, fuel rails, sensors, fittings, and accessories. This
intake manifold provides horsepower and torque increases in the idle to 5500 rpm range. Other features include a removable plenum cover allowing
access to runners for modification if desired (not needed for operation below 6000 rpm), and CNC port-matched upper and lower manifolds for
maximum flow efficiency.
