Refrigeration lines
Fuel lines

4L80 crank spacer if new enough to keep OE v6 tranny
or swap bell housing and front pump on existing tranny
v8 transmission dipstick tube
Harness pcm/tcm thats exact year of vehicle to keep gremlins to a minimum

You'd be money ahead by selling your 2013 and buying a rcsb with a v8 already in it. I don't think you realize all the work and money involved in this swap.
The computer in my '03 is a slow piece of ****. I would never swap a newer computer for an older one.
Also, there is a box that will allow the computer for a newer engine work with a 24x reluctor wheel. Lingenfelter makes one, not sure who else.
