I think I might have screwed up.

[Fulcrum]

It dosn't have a pan and I don't see anything obvious. I guess I'm more concerned with the rear seal having been mashed by the impact or maybe the crank being knocked out of alignment.
I have worked on a few engines in the past but I've never taken apart or re-assembled the block before, I've always just taken them and swaped them out and going from there.
I've been reading, and I think I could do it being there are no time constraints on this project. Do you think it would be prudent or would it be a waste of time to take it apart and reassemble it? If I do take it apart should I have it checked out by a machine shop?
I have a different cam that I wanted to use anyway, besides if it is a stock '85 cam, wouldn't that be a roller cam, and just how could I verify that.
