Hey cool, thanks guys. Yeah, my motor has some life left in it but I can feel it getting tired so I'm just trying to figure out what route to take...basic rebuild with some mild upgrades over stock on my existing engine or and get another block and just start on a real performer to build and drop in so my truck doesn't see much downtime. And Armond, when I get my off-road Jeep project rolling, guess what engine I may look for to base it on, lol, thanks for the link.
