That's is very true B. It is very expensive
Taken good care of your equipment will definitely make a huge difference in how long it stays together.
I run my 540 at 30 degrees timing and leave at 3800 rpm and shift at 6800 and we put 520 passes on it before we pulled it apart and it was definitely time well it was over due the lifters was completely warn out i just got lucky that they didnt fall apart i want run it that long again before it gets freshened up.
but like the guy's said if you abuse it you will lose it
