We never lost a Shubeck without there being a reason outside the lifter itself. Of course, I treated them like they were the finest crystal. And I was obsessed with valvetrain control and maintenance. Honestly, if I could get someone worth a damn to make them, I'd use them.

I've run the same set of Shubecks since I put the car together 12 years ago and they don't look any different than when I installed them. When I picked them up in Shubeck's shop, he did tell me to run enough spring pressure to keep them on the lobe so I've always run more spring pressure than I probably needed to.
As a hydraulic lifter there is not much room for a thick carbide puck on the bottom of the lifter but with a solid lifter there wouldn't be the same restrictions I have to wonder if a less fragile version of them could be developed now that we are allowed to run solid lifters in stock.
