I guess we are not understanding why the diesel pounding is more damaging than a gas engine's pounding.

what rpm would you be running each of these theoretical engines?
a 2015 escalades 6.2L can make 460lb-ft@4100rpm ...and 420hp
a 2015 duramax 6.6L can make 765lb-ft@1600rpm ...and 397hp
if you could get that escalades engine to make 765lb-ft@1600rpm by what ever means necessary ... i wouldnt be surprised if it could take it for a while, but i think the knock/ rattle of a diesel on top of that, from an increase of pressure so sudden it bangs, is what i think would really shorten its life expectancy. which was why i was thinking pilot/ multiple injections would be helpful
