PerTronix Ignitors for GMC Trucks, U.S. & Canada

Type	Usage
Standard Ignitor	Normal driving w/stock or mildly modified engines. Good performance potential - customer cars run the 1/4 mile in the 11s with Standard Ignitors.
Ignitor II	High performance street and racing.
Ignitor III	High performance street and racing where multi-spark and a rev limiter are of benefit. In addition to high RPM benefits, multi-spark will also enhance low RPM performance on engines with big cams.

Suppression-type spark plug wires required.  Do not use solid core wires.
