Lifters In Stock Eliminator

For anyone who thinks it is okay, or thinks it is a "gray area", people have been DQ'd and suspended for it.

Oh, just write Glendora and try to get a letter on official letter head accepting/allowing it.

Funny thing is, if you don't have the cam lobes designed for the bigger lifters, you're not gaining anything, you're just illegal for no reason or advantage. There are probably some lobes out there, but are they even the lobes you'd actually need, and are they even modern designs that are fast?

Thanks for the replies. I think I will staying with the .842 dia lifter. Im just making sure i'm totally legal.
As far as lifters themselves what are the best tool steel solid lifters out there?

If bigger diam lifters, bigger cam diam didn't work , SS,comp and Pro Stock would not have lifters over one inch diameter/ huge wheels and 70 plus?s mm cams. It is a performance advantage.

Yes, and if you can't increase cam core and/or lifter diameter, lofting the valvetrain reduces friction and adds hp, but some prefer keeping the lifter in constant contact with the lobe.

In a thread on another forum they were talking about that many years ago Isky sold "Chilled Iron lifters". If someone today could manufacture these it might solve the problem.

The Isky chilled iron lifters are not harder than either the tool steel or the Johnson Hy-Lift hardened tappets. The only thing harder is carbide or ceramic.
