Too much endplay question.

Ok guys, i was helping a friend changing a cam in his 318. When pulling the lower timing gear off, I noticed that the crank has alot of endplay!
I would say that it has a good .090 of endplay! The engine has always run fine and has good oil pressure. What kind of problems do you guys see with this? We planned on swapping in a new high stall converter, would this endplay cause any problems, with the converter to pump engagement? He is building a stroker 340, but it wont be done till sometime next year. What kind of other problems could this cause?
Thanks
