The 3.4 L SHO V8 was introduced in the spring of 1996. It incorporated many of the traits of the SHO V6, including the aluminum cylinder heads and 4 valves per cylinder DOHC design, but differed with an aluminum rather than iron block and no variable length intake manifold. A chain is also used to time the camshafts to crankshaft instead of the belts that the SHO V6s used. The SHO V8 has a split port style intake valve setup. The primary valve is exposed all the time and has the fuel injector spraying on it, while the secondary valve is only exposed when the Intake manifold Runner Control opens the secondary plates at 3400 rpm. These secondary valves are called "secondaries" by SHO enthusiasts. Power was similar too, at and of torque.
