Thought I would write a missive on the state of oils in the 21st century.
the state is bad, even with ZDDP, and break in oils we are seeing camshaft failures at 2000-2500 miles. --
we have had 2 FEs come to us with wiped lobes in the last 30 days *WITH* approved treatments in the oils.
Comp cams has even included a printed document with each flat tappet cam they sell.

-- we now have a source for a FE roller cam (hyd roller) that works well and we have a grind that is a rollerized C8AX design, with some modifications for the larger engines of today.
hope this helps , will post pics as they come up.
