  1. Kind of like replacing a water pump on a car with timing belt. You have to remove fan belts, shroud, plastic cover, and timing belt first. Getting there is most of the cost. That's why you always replace water pump while replacing timing belt. You are already there. In this case, getting there is most of the cost.

  2. I have seen video - think it was Wheeler Dealer - specialty shops have the ability to test fire injectors on the bench. A good one looks very different from a bad one.

  3. The center of gravity is important. In Graveyard Cars, they make sure to install rear end before installing engine when putting car back together during a frame off restore. If they don't, it will fall off.
