Realistically, most (nearly all) of that stuff is worth more per pound. The top load transmission cases may be worth more then scrap if they look better on the inside than the outside.
Not total junk, those housings have lots of uses and the transmission stuff at the least would be cases and small hardware and I believe I saw some exh manifolds in the pile.
If nobody takes the generators, the copper winding is worth a fortune in scrap value. On the other end of value are the fans, not to be trusted without very careful inspection for cracks, and even then, hold your breath!
