Too much endplay question.

Look down at the main thrust bearing and see if it is ate up on the front or the back. A big converter that gets hot swells up and pushes on the crank from the back.....

IMO, .090 isn't that bad, really. With the cam out, pull the crank in and out and look at the rod side clearances, and make sure the rods aren't moving on the crank bearing, only the piston pins. (binding) If you're good there, run it!
