4.7 is a overhead cammed diamler/mercedes designed POS. That is the highest mile 4.7 I have ever heard of. They are not a comparison to the 5.2/5.9 magnum engines as they are complete junk and you cant put them in anything, nor would you want to. The trans is not a 42/44/46 RE/RH, its a 45RFE which takes its own pcm. They are only slightly more notorious for exploding than the 4.7. The 4.7 is famous for cams seizing in heads,cams breaking in half, cracking heads, they toss rods like angry toddler but at least they make a pathetic 200 hp and get 15 mpg unless you happened to be the unlucky bastard that got the Chrysler "death flash" then it was 10 mpg sitting in the drive way. Ask me how I know:banghead:
Comparing a 4.7 to a 5.2/5.9 is like comparing a turd to a cup cake. Oh, by the way, I dont really like 4.7's ....sorry for your loss.
