Check the tension on your timing belt as well as your cam timing, it sounds like the belt might have slipped.

I had a timing belt break on my Thunderbird Turbo Coupe. It made the same kind of noise you describe when I cranked it. Some of the valves were stuck open, so the starter was working against far less compression than usual.
