Just my opinion
Anything made by man can go wrong sooner or later, so sure some may "blowup" for one reason or another same with any engine ever built. Some sooner/some later.
People will say the 6 Jeep used for years is junk yet I've ran three up over 260,000 ( one 265,000, other two over 300,000) and no problems at all, never had the valve cover off of any of them.
Maintenance is key no matter if its a lawn mower engine or a fully built/balanced/blue printed BBC.
As far as running them hard, I'm with Troy you have to "exercise " them daily.
One of the first Harleys I had back in the 1970s I rebuilt with the help of an old Harley mechanic, when I got it back together he stopped over and I said something about riding it easy for a few days. His response was "I know how you ride everyday, you've never given it any slack before, so break that :favorites68:shovel in the way you're going to ride it, if its going to come apart, it'll come apart. So break it in right!"
My 3.7 is over 162,000, 03CDKJs is at 186,000, T-Birds is I think 185,000 or so, thats just three off the top of my head with no issues.
Run em till they blow then upgrade!
