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.

.670 lift and 7400 rpms with no issues. Bone-*** stock $110 a set ls7 lifters and nice 3/8 pushrods

Unreal

.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.
