727 trans rebuild

I am in the middle of rebuilding a big block 727 trans and I have a few questions. First; I have all the clutches and bands back in the case and there is very little end play on the input shaft only if I pull really hard on the end shaft does it come out about .050" I am guessing. I put a .098 thrust spacer between the pump and front clutch. Both shafts move without binding. Second; How much play should be in the clutch packs after they are assembled?

Thanks for the help,
Cory
