Solid Roller Lifter Selection

I was wondering more about a tech paper with scientific tests on longevity with test engines running for days in a clip.

Just think of the countless millions upon millions of miles that have been put on by OE built motors....... using lifters that don’t have .800 wheels(like a G3 Hemi with its .842” diameter lifters).

The main point being........ not every application requires parts selected from the bottom of the page.
