Jeep Strokers

So as it sits right now my block has .040 over piston size. To get the proper quench and all that jazz .060 over is looking like the route I might have to go. For the guys that are running motors with that size bore how many miles have you put on the engines. I am just thinking longevity, I dont want to put the time and energy into this to have it have redo it in a couple of years. It is an 88 block and I will be rock climbing trails along with days in mud trails.

Thanks in advance for the help

Going +0.060" in a 4.0L block isn't an issue.
