120k on my 5.3 and no issues yet!
125,000 on my 5.3 and about to have 7psi thru it until i get a boost controller...
Well the vortec 6 cyl multiport was first used in 88, I think thats what he was getting at. And since then have been rated top engines.
But 96 was the first year for the roller assemblies.
