A plain Jane LS Camaro puts out 455 net HP bone stock, a ZL1 puts out 650 net. That's over 500 and 700 gross hp in a car that has AC, will idle all day in traffic, and will go 200k miles easily. If you can figure out how to do that with any Mopar engine I'm all ears. Maybe with modern machining practices 200k is possible. A Mopar can certainly make those HP numbers no problem, but I have a very hard time believing that they can do it for very long. EVERY hot Mopar engine I've ever dealt with personally or even read about is far from build it and forget about it. They're a labor of love that require constant attention. There always seems to be a valve train gremlin, broken block, or some other issue. But there definitely is a mystique to a Mopar.
I have built many small and big block mopars and all are still running and very dependable, If your braking things all the time than I have to believe it's something else. You have to know the limits to the parts you are using and sometimes trial and error gets very expensive. I just fixed a oiling problem
that was caused by a part that was purchased at Mancini's to fix a different problem, It fixed one problem but caused another. I had to scrap it and make my own and now both problems are fixed.
