i was wondering what all needs to be done to make a 400 to a 440 besides re-sleeving the cylinder and getting the 89mm piston kit?

you basically covered it. put the sleeve in, bore the sleeve to match the piston, gap the rings and install it. if you want a power increase, add a cam too.

I hope my 440 turns out good.. I called FDO about head studs, but couldnt get any one today.. From what I have been reading bout it.. I should be in the high 30's or low 40's on horsepower...
