72 K20 4spd ls swap

Working on a 72 K20 with a 350 and 4spd set up with my son for his first vehicle. Want to make a reliable driver for him, this 350 would need quite a bit of help to be reliable. I put a 4.8 in my 72 C10 a couple years ago and love it. What sort of extra challenges are involved in putting a 5.3 into this 72 k20 with the original 4spd? Also this truck has a 4" lift if that helps with clearance issues.
