Hey everybody just finally joined the forum after snooping around for a while.. Hopefully i won’t be shunned as i’m actaully the owner of a 5.9 ZJ.. just got done with a tedious t56 swap early this summer and next on the list is to crack open that engine. There seems to be a lot more good info on 5.9 performance here than on any jeep forum so here i am! Lol. Just wanted to say whats up to all of you..
