The rule book is a bit out dated, but how can you not allow a car in the guide to run the same equipment as it came from the factory? Would tech bounce a purely stock LT1 because it has a crank sensor?

I do understand the argument that you could consider a crank trigger as being some sort of crank position sensor. The issue is that the crank sensor was not used to fire the ignition in Lt1 cars. Lt1's weren't actually fitted with a crank sensor until 1996. The computer still is only using the camshaft position, determined by the optical sensor behind the distributor cap, to fire both the spark and injectors. The crankshaft position was actually fitted to detect any misfires by using crankshaft speed and position to determine if there is a slight drop in crank speed at a certain interval.
