I did a 2012 6.2/TKO 600 into a 73 Z28. It was a great swap. On the Gen V LS engines you have to add a power steering via the after market. Your 2018 6.2 has electric power steering. Also it should have VVT and DOD so you need to decide to keep or delete. Some keep the VVT but most delete the DOD do to some lifter failures.
