Lots of people have done a 6.4 manifold swap onto their 5.7. It’s a super easy bolt in swap. Only need to extend the brake booster vacuum line. I would buy the srv harness extension with the manifold to make it even easier otherwise you need to splice the harness to extend it. I even have a way to install a catch can into the manifold if you choose to do that. I purchased a stock 6.4 air box to go with my swap to keep everything 100% factory parts

Definitely recommend the mod as theres a noticeable difference. I could only peel out my 37s just a little bit beforehand. Now I can keep it going a good distance qnd go through my expensive rubber quicker if desired.
