I heard some say the 7.3 is not as skookum as the old 6.9
some even have a weeping cylinder wall that leaks oil into the coolant passage.
I had a 7.3 once I saw black gunk inside the rad, i didnt understand what it was then, now i guess it ogt to be some oil in the rad.
my 6.9 touch wood is clean with green anti-freeze.

are the 6.2 or 6.5 gm better?

my fnd has a 6.5 turbo, he has to re-locate a module away as it orig position was too hot for it.

TIA
 
Only real disadvantage the 7.3 has over 6.9 is that it's more prone to cavitation, other than that, the newer style rockers and 1/2" (6.9l has 7/16) head bolts make the 7.3 my first choice
