3.8 is short deck. Not gonna happen. 4.5 not sure. Better with the original cover and the old distributor I would say. But in the long run you should ditch the distributor completely and go coil on plug with ms3 x. You can get a crank trigger wheel from DKUBUS for it.Are you planning to put the timing chain case cover from the 4.5 on the 5.6? Does it fit? Maybe get a timing case cover and distributor from a 3.8 to be able to use the older simpler ignition? ?? I don’t know.
