Crane roller conversion kit - Who's using it and what cam are you running?

[5cu11y]

The "retro fit" kit isn't really necessary anymore. Anyway, I think I still have one laying around. It served its purpose.

Quality aside, these lifters are just the same as any other hydraulic roller lifter. I don't understand what "aren't good in the upper RPM range" means.

My setup was Crane and Booth and I never had a problem. In retrospec though, I will never buy Crane again. I don't think they really make anything except stickers. Which means the only tech they can provide is on sticker adhesive vs. temperature or something.
