Blown 6.0l to 5.3l engine swap
 

A friend of mine has brought his 05 with a 6.0 that has blown. He has a 05 5.3 out of another 4 X 4 and wants me to swap it out. What is involved in doing the swap and any programming of ecm will be needed. I have read several other sites where everyone says it stupid but it's what he wants so please no comments why hes crazy and should buy another 6.0. Thanks in advance for the help

Just a reflash should be all

Thanks
