well I did the search thing, and the general consensus is that gear drives made for roller cammed cars dont mess with the knock sensor. I am planning on installing a cam over the winter and need a new timing set and was thinking about a gear drive. I havent seen anything about anyone using a gear drive with a non- roller TPI motor. If there is a good chance of problems I will just get a cloytes timing chain set instead.

Yeah, if you get the "quite" gear drive, you should be fine. I know a lot of people running them without problems.
