Checking over on the hot rod side Challengers etc, it looks as though it fits. However PCM will have to be flashed so the info it is getting is correct. I dont think it would be easy, but deep pockets would help. Check the inter web and do some searches for something like truck engine swaps and see what comes up.i own a 2016 2500 5.7 i am wanting to do a 6.4 swap. All the blocks i’ve seen for sale have the 8th digit as a J my 8th digit on my truck is a T. Does this matter? Would it still work?
