Well, more accurately, it would likely pick up false knock and retard your ignition timing, albeit you can disable the knock sensor(s). Mine is.
Nevertheless, I've only heard of two people ever using timing gears on an LT1, and they both ended up getting rid of them. They are not recommended, and most likely require some specific modifications to work (of which I'm completely unaware). I'd do yourself a favor and stick with a chain drive.
