Cam 02 Z
|
The traditional Chevy V-8 uses a single camshaft in the block, unlike this dual overhead cam Vortec 2800 I4 with coil-on plug ignition. Engines such as this employ no pushrods and have two dedicated camshafts: one for the intake and one for the exhaust. Overhead cams reduce valvetrain weight and provide more positive valve action.
