I agree it would be nice but it is a nice option for power the 6.4 truck manifold is the best stock intake for power more plenum volume and srv ram guys on the dyno saw 40hp over stock 5.7 ram intake. I had a 15 ram R/T i built and got lucky and scored 2 6.4 intakes for 125 from someone local sold one and kept one for myself it was a great simple power adder and would work under a hood better than the 5.7 truck manifold does. If your doing a gen 3 though i know your seeing the dollar signs add up custom grind cam and everything to install, hellcat lifters, psi valve springs retainers and keepers, 3/8 chrome molly pushrods, 1 7/8 long tube headers to 3 1/2 primary, 6.4 manifold, cold air intake the used the hood scoop to feed air to the airbox with a k and n style filter and the tuning i probably was minimum 4 grand in parts i did all the labor myself.
