2015 silverado rcsb 4x4 4.3 to 5.3 swap

[15-4.3]

Looking to get some input on what all is needed for this swap. Thanks in advance

There will be more to this small list but the basics are here. You need the engine, complete wiring harness and fuse block assembly. Probably going to need different radiator hoses and stuff like that.

 

I advise you to find a 2014-2015 engine/harness stuff because the later trucks do have different wiring in them and they changed stuff in the can-bus system for communications with the BCM etc etc.

 

Of course it would require a tune as well to make it all function.
