97 K1500 5.7 to 6.0

Hello everyone I have recently bought my first truck back. It's a 1997 Chevy K1500 z71 with the 5.7 vortec. Being a young man at the time active duty in the military the truck had some abuse. Started having engine issues with it and got tired of being under the hood every couple days so I sold it. Now that I have it back and settled down had time to miss and regret selling the truck now I want to fix it up. My issue is that I want a 6.0 in it going for the ls based 6.0 I have no idea where to start or what parts I'd need to do the same I've done mechanic work all my life turning wrenches isn't an issue at all I would just really like to know what all I will need to make this swap possible without and setbacks or upsets
