Just a better lifter and better sustainability at higher rpm

Pretty much this is all.

The original LS1 lifters were discontinued & replaced by the LS7 lifters, so technically you cant even get "stock" LS1 lifters anymore. Its LS7's or aftermarket.

If you look at the bottom around the roller area, the ls7 lifter is beefier.

This is interesting....I may have LS7 lifters already in my engine. It was produced in the 2006 arena...

I personally am not sure that the LS7 lifters are stronger than LS1 lifters. At the moment I'm 99% sure I have a trashed LS7 lifter in my Camaro that's making the engine sound like pure hell. Car's currently on a boat from Germany to the USA.

Anyhow, I did a H/C swap 22K miles ago and swapped to the LS7 lifters then. Car ran a lot at 3000+ RPM on the German autobahn and road courses like the Nurburgring, but RPMs never exceeded 6500RPM. That said, if the LS7 lifter was stronger, you'd think they'd last more than 22K miles. Hell, the LS7 has a edline of 7K.... so go figure.

Just my $0.02.

Alot comes into play with lifter life as well.

I have had my LS7 lifters & my Patriot Gold duals in for 80k miles & still runs just fine. did my H/C swap with the springs/lifters at 100k miles & now rockin 180k miles. Never had a single issue although its close to time for new springs.

Also, most guys run cams way bigger than the 7.0L cam in the Z06. Bigger cams with more lift and higher spring rates wear stuff like lifters out.
