1993-1995 Ford 4.6 V-8 Modular Engine
This engine was introduced in 1993 in the Mark VIII. This was Ford?s new modular design engine which utilizes some of the same parts to create a lower horsepower engine used in other Ford models. The 4.6 engine in the Mark VIII utilizes a thirty two valve, double over head cam design to create 280 horsepower while the 4.6 in other Ford models is a single overhead cam engine that produces 205 horsepower. The Mark VIII engine has intake manifold runner control solenoids which operate plates which are closed below 3000 RPM so the engine is running on two valves per cylinder. With no air delivered to the secondary intake valves, economy and emissions are improved at low RPM. Above 3000 the plates open increasing air delivered to each cylinder for more power on demand. The 4.6 engine has two ignition coils with each coil firing four cylinders. The 4R70W transmission is used behind this engine. Factory ECM can be used in factory configuration.
