A distributor consists of a rotating arm ('rotor') that is attached to the top of a rotating 'distributor shaft'. The rotor constantly receives high-voltage electricity from an ignition coil via brushes at the centre of the rotor. As the rotor spins, its tip passes close to (but does not touch) the output contacts for each cylinder.

The LT1 uses a new engine block, cylinder head, timing cover ...

This assembly, called the "pole piece and plate" in the parts book, should not be disassembled because the pole piece is centered around the axis of the distributor during production. This sets the clearance between the teeth of the pole piece and timer core. There are seven different pole pieces and plate assemblies available.
