Question LS2/LS7 Lifters
Would these work in an LS1 as a replacement...would they be any better than the stock LS1 lifters?

They claim 8,000 rpms, but do they really support that? I thought hydraulic lifter collapse after so many rpms.

Seeing as the motors they were used in do spin to 8k RPM I would say they can. Weather or not a lifter collapses depends on how the rest of the valve train is set up.
