Schubeck Lifter Update

[Fishlips]

I have never run the Schubeck lifters although I do have two sets in the garage for an upcomming Stocker project. What type of pushrods are you running and what is the possibility that the stock rockers and pushrods are flexing enough to allow the lifters to smack back down on the cam instead of following the ramp? Another thing, you mentioned. You thought you had punched another hole in a rocker arm. Was this lifter on one of the lobes where you had a rocker arm failure?

I have found on my super stocker (the hard way I might add) that if for any reason the rocker arm comes loose and the lash gets big, breaking a rocker arm or anything, then you must replace the lifter on that cylinder. It is going to break!! It may not happen that day or even that race, but within a few runs it is going to destroy the lifter!!!!!!! I have had this happen enough to realize it is a must to replace the lifter after it has run uncontrolled on the cam lobe. I believe the cam smacks the lifter and damages it.

Maybe you had previously damaged the lifter and after a while it fails.
Just a thought!
Good luck!!
