Is the way the Ford engine is installed standard in some way, or does it take 5 years for a Ford engine, 5 for a GMC, ...? Cuz if it's unique to Ford, it's a Ford problem, not a trade school problem.
Looking for book time, etc, ford doesn't seem likely to be as high complexity as similar large diesel.. I think the issue is similar to workstation repair vs PC repair.. 5 years learning this is instead of making a similar hourly rate on higher volumes of cars, risking that others are trying to close that gap too and wondering how long that skill as it is stays stably useful.
