Lippy,
Same specs as posted. Comp Cams was the first lifter that failed. Broke the roller off of two lifters and when I pulled the engine there was another five lifters without any bearings left in the rollers. After calling Comp Cams and telling them that I got less than 1000 miles on their lifters, their response was.... that's great, those lifters are only supposed to last 800 miles and the springs 1000 miles. Every manufacturer that I talked to told me I couldn't run those spring pressures on the street. When I talked to Crower they asked me if I was happy with the springs I was running, and I said yes. They said keep using them because you won't have any problems with our lifters. I've been using them for the last 10 or 11 years now.
