That one was the noisiest gear drive I've ever heard Steve! I'm also pretty sure it was the culprit that took out my bearings and caused the 327 to spin a rod bearing. I wish I'd demanded the engine builder put a gear drive in the 4 bolt main 350 when I had it built for the Austin. I miss the gear drive in it and the whine of a good one. Too much work to swap one in now, so it will never be done by me.trip down memory lane Vall, thanks for sharing. Love those gear drives!!
