"Let those 5.3's eat".
Typical small block GM....likes to..... actually "loves" to rev. You could run that sucker at 5K rpm for the rest of it's days and not hurt it.
Our 6.2 in the Silverado likes to rev too.
I am looking at replacing the aging Frontier this year, and high on my list is a new Titan 5.6 gas in a XD trim. I've driven one ( not towing ), and that's another engine that likes to rev. Stick your foot in it coming onto the freeway, and it'll happily rev on out to 5500. Sounds awesome. Pulls hard. What's not to love ?
WTH, I often see 3000 rpm and 28 pounds of boost with our powerstroke when I have the big horse trailer on it. Ok....again, let it rev, doesn't hurt a thing ( except fuel burn ).
