Advise on Schubeck all Ceramic Solid Lifters
 

I have a set of Schubeck solid lifters that are all ceramic. My question is are these a safe alternative to use on a Stocker camshaft? Will a Cast cam work or do I need a Billet cam? I know you need to keep close to 200 lbs on the seat so they don't bounce. Anyone using these? I'm Trying to get back into Stock after 25 year layoff.

I don't know if the solid ceramic lifters are actually legal. I'd get it in writing, if I were going to run them. We own a set, I keep them for burnishing/breaking in cams. We have steel lifters with ceramic feet we use to race.



They work fine on a cast cam, provided you can find anyone who has good cores. I was using Comp Cams P-55 Lobe Lock cores, and having them nitrided. Use moly lube when you assemble, and good break in oil when you start it.



How much spring pressure you need depends on the application. In a big block Chevy, I never get below 250# seat pressure, if I do, I see the exhaust bounce on the seat.


Treat them as though they are your wife's fine crystal heirloom set. They absolutely don't like any sort of impact. If you break one, your short block is absolutely toast. It's like throwing a handful of crushed industrial diamonds in the oil.
