LS Gen 4 - LC8 engine questions

Looking at a zero mile LC8 engine - it has no wire harness, ecm, throttle pedal ect….

What controller and wire harness, pedal will work, probably a dumb question but this is my first LS swap

Stock the engine made roughly 350 HP and 375 FTLB - what can be expected with a tuned ecm, headers, ect.

Any concerns with this swap?
