Okay got the lifters out just now...4 of them failed.. clips completly gone, not even in lifter valley, I hope they just fell to the pan..going to change oil, the lifter insides of the 4 fell apart when I pulled them out... maybe there is my power loss problem... going back to stockers...

 

which lifters, the 875's or the 850's?

 

they were the 875's...

 

ok wheew. I have the 850's becuase of all the problems I have read about. From what I hear the stockers, or stock replacements work fine. Mine are working great (850) in a 58X lift motor. Give em a shot!

Nevermind, I see you are installing the factory ones... Im stupid.
