Has anyone had problems using OEM distributor gears from year-to-year? I have installed junkyard distributors out of Jeeps (Motorcraft distributors) into early engines and have had no problems, but I don't want to ruin an engine either. Is there a tell-tale noise the engine makes when the parts are mis-matched or self-destructing?
Thanks
