904 band adjustment for a 408 stroker???

Hi, I have a good 1979 chrysler, lockup 2300 stall converter, 904 transmission I am using for my 1970 dodge dart swinger street car. The transmission was linked to a 318 before. I would like to know if there should be any band adjustment changes to match the extra 90 cubes and the 200+ more horsepower... I now have a 408 stroker to go in the 318's place.

-(PS) For the future, maybe the near future..lol, I would like to know what exactly to install in it to beef it up so it will last...unless it will on its own the way it is...bone stock??

PLEASE ADVISE!
Thank you,
