The heavier and longer, the better! Several years ago two students at the school where I taught were just finishing up an assembly of a 235. They had dismounted the engine from the stand, bolted the bellhousing, flywheel and clutch on it, AND PUT IT BACK ON THE STAND FOR SOME REASON! As they were working on the manifolds, the stand tipped over forward and the engine hit one kid on the foot. Several broken bones and 40-something stitches later, he still had a foot.
The policy in the shop was that students had to wear full-coverage leather shoes in the shop. One day before the mishap, the kid had been punished for wearing tennis shoes. The day of the accident he had come to class with heavy work shoes on. That difference probably kept him from losing at least part of a foot and being impaired for life.
