6.4 truck intake manifold and 6.4 stock air box is installed. Currently running 5.7 injectors with spacers. Now need to get a tune so I can swap in the 6.4 injectors and delete mds. May just have to buy a pcm from diablo... wanted to just unlock mine but may have to go the easy route. Can’t let my truck be down anytime soon. For anyone interested the 5.7 fuel rail does fit but needs a new hose for the crossover. Was a 5/16 high pressure fuel and transmission line. Also, drilled and tapped the 6.4 manifold to run my catch can. There is no way stock on the 6.4 manifold to run a catch can. If you look in the pictures you can see I drilled the egr blockoff plate and install a 1/2” barbed 90° fitting with a 1/4npt thread into the blockoff plate. The pvc side I drilled into the stock pcv housing and tapped it for another 1/2” barbed straight fitting with a 1/4” npt thread and just plug the stock vacuum port into the manifold so it only sucks through the catch can. Either jb weld or another form of putty should be good as long as it’ll harden and adhere to plastic. Posted in my build thread as well. This is with plans to install a aev snorkel in the future.
