LS7 Lifter limits

I'll start this thread as to not Hijack Tainted's

I'm planning on using LS7 or Sealed Power lifters. What are peoples opinions on their limits? Lift and RPM? I see a lot of guys with turbo combos running them and even in some cases using the stock lifters that originally came in the engines. Some of the cars are spinning 7500+ and going well into the 8's.

BTW I am building a turbo combo.

.650 lift, 7200 rpm, 900+hp no issues. Several shops told me they use them for anything up to 1000rwhp. After that the high end morels is a good choice but they are ~$800+

Practice shows only Lunati Signature Series lifters do their job well.
They are top of the line.

LS7 lifters are more than enough for about 90% of the builds on this website.
