2014 4.3 swap
I am pretty sure there are a couple of these swaps out there, and in my opinion there needs to be many more! This engine is a beast, and I believe Sloppy Mechanics turbo'ed one a little while back and made well into the 400's without issue.
As far as your swap, if you keep it drive by wire, you should also get the pedal, and TAC module from the same vehicle you got the engine and trans from. I'm not the most informed on the swap, but if you search for what others have done it should at least get you started.
