Ok so when they say. “Crank/cam”. Are they counting the optical
sensor in the optispark as a crank or cam sensor? Because the earlier LT1”s do not have an actual crank trigger mounted in the timing chain cover. Like the later models do. They rely totally on the optispark to handle that. Not nitpicking. I own one and want to make sure I’m ok.
