Are you familiar with the 1992-1997-8 LT-1? It has no distributor! It has no place to put a distributor! It is unlike any other conventional small-block Chevy. The spark and fuel are controlled by a "crank" position and a cam position sensor through the ECM.
Interestingly enough, in GM F-body shop manuals, they actuall refer to the optispark unit as the "disributor ignition system."(see attatched) I don't believe one could quite classify it as a "crank trigger" looking at the way it works. Correct me if I'm wrong(being that I am primarily a FFFord guy), behind the cap there is a rotor that uses slots on a gear with an optical sensor to determine when a spark should be administered. This sounds to me to be more similar to a "hall effect" type distributor used in 80s fords and chryslers rather than a traditional "crank trigger." IMHO the rule should be written to include all fuel injected stockers in determining if crank triggers are allowed in stock or not.
