No blocks aren't prone to exploding. The late models can possibly have a head from a bad casting. Search for info on 0331 heads. But take it with a grain of salt, mine has 180k and no issues and theres others that have more on theirs.

95 here w/ 190,000ish, original motor and trans etc... runs like top!!! Lots of hard driving, but well maintained for the most part. With all the other high milage #'s I'm seeing, it sure makes me feel better about my rig! My goal is to make it to 250K.
