Bravo, everyone knew the rules when they requested their permanent number years ago. While at the time I applauded the unlimited valve spring rule, it is a major reason contributing to runaway costs in stock eliminator. If you don’t agree with the rules OR heads up runs , JUST LEAVE ….run superstock, brackets ,….WHATEVER . ….Take your personal agenda with you as you close the door ……

Bubski can't believe this crazy train has derailed into a no "heads up" no performance based category !! Now back to lifters !! Imagine adding to the vegetable soup of stock classes with additional classes for cars with or without roller lifters ?? Bubski would like to present an example of this fine mess being pushed in Stock !! How about rU/SA the "r" being for the roller lifter designation !! Sooo!! how about f-U/SA ?? pretty self explanatory I believe !! The f-U/SA class will be 6 rounds at any class racer if they do this just because !! Cheers !!

Sorry Bubski but I can't get behind *-*/SA, it's too close to something some woker would say for me.

Nope. Cam is junk. Lifters are junk. Oil pump is junk. Pistons? questionable if they can be saved. rod and main bearings, rings. All junk.
The problem is getting lifters that will last. Coating does not work. Tool steel on certain cams won't work. Seems only thing that will work (sometimes) are 15 year old lifters that are not available anymore.

Here's a good take on the lifter problem
