LOL, crazy is always a good option. I'm sure there a few writeups in the FAQ or tech section

The real question is, what was his mileage and service history of the belt?

A comment....

Not a waste of time, but you can pretty much guarantee bent valves(especially if he was on power). Infact , you might not even be able to get a full test(compression) done, due to the fact the valves are bent and bound up between the head/guide. See the if cams will turn over a full revolution.
Sorry to hear about your brothers car, good luck.
