Lifters In Stock Eliminator

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.

Titanium is entirely unsuited for a sliding interface application. Especially against cast iron or steel.
