I have acquired a 6.4 hemi intake from a wrecked truck at work. I want to swap to swap it out on my 5.7. I know I need a EGR block off plate, injector spacers and a wiring harness extension. Is there anything else I would need. Also where do I need to run the hoses since the 6.4’s are setup differently

Can I also run the 6.4 throttle body or do I need to swap it also

Throttle bodies are identical. All 2013 and newer 5.7's /6.4's including the 485 horse car 6.4's all use the same 251 throttle body. You'll need a differant airbox,i'd also look into replacing the intake O-rings.Search CrazyKids posts,Khris already has a write up on swapping the 6.4 manifold.
