what is the general consensus on cylinder pressures?

I've worked on my buddies 3.7 wrangler more times than I care to admit. Both the 3.7 and 4.7 are among the biggest piles of garbage ever produced and Chrysler just shoved the god awful disasters in everything for years with no other options. Overheat one to the slightest degree and your tearing it apart or throwing it in a crusher. Impossible to repair alot of basic stuff without pulling heads, intake, or other unnecessary items just to get to things. They burn oil, leak, rot, wiring is atrocious, computers fail hysterically frequency, crack, explode... I'd rather have a 2.9 then a 3.7 or 4.7.

the jeep community seems to swear by the 4.7 as long as you "take care of it". your are right tho, they have a laundry list of issues. when i first tore this thing apart, i looked into various "recommended" engine swaps. there are none, just more shitty 4.7's guess its impossible to put a 4.0 i6 into a 4.7 jeep and make everything run. 318/360, no they dont recommend that. << i was hopeful i would find a nest full of threads on the 318/360 swap. there arent even many ls swap threads. but i atleast know there is enough aftermarket for the ls engines that i can make that one work.

Its back... guy now wants an engine. I said ok to replacing the engine but he needs to buy one. And zero warantee through me. Explained it clearly. You bring me a motor I put it in, if it fails you dont come to me... I should not have taken this job but I need money.

idk about those models, but i know on the wj that the front core support is removable fairly easy. if you just get a motor the swap should be fairly simple.

That's why they're called the "Powerturd". Don't get me started on the "3.6L Pentastank"

This is true. I pulled the engine out and put it back in when I the crank in my KJ all by myself. Just me and my Harbor Freight 2-ton hoist. Bell housing bolts were a pain but I did it and I'm not that clever or talented...
