Hello first post here on LS1truck sorry if I am in the wrong thread! But to get right into it my 08 sierra appears to be suffering the dreaded AFM piston ring issues and instead of rebuilding my engine I want to go a little different route. I have access to a 2004 or 2005 Yukon Denali with the 6.0l and 4l65. The truck has been parked for about 6 years as the oil pump crapped out and it developed a lower end knock while idling in the winter. It wasn't driven after. My plan is to pull the motor from that and rebuild it for my truck. I intend to replace the crank with a 58x varient, have my 243/799 heads rebuilt off my 5.3 using ls7 springs and put a small cam in the new motor. I am wondering what all will be included in this swap? Thanks so much! -Alex
