If i put 20 inch rims on a 1977 chevrolet impala will it mess my transmission up?

[the one and only]

i need to know because i plan on doing this what will be the cosequences?
if i went with 22 inches instead which one would be better for a driving every day use?

Putting 20 wheels on any car isn't right.

probably will have to beef up the springs and shocks
clearance might also be an issue
