Joe H.,
The old used LIFTERS from the original cam
were used on a NEW CAST camshaft.
The old lifters were intended for a FORGED STEEL cam.
Correct break-in procedure was not followed
&
there was lifter face to cam lobe incompatibility.
I disagree that if the correct break-in procedures
were followed everything would have been OK.
He still had used & the incorrect lifters.
Oil chemistry & correct break-in can't overcome the
use of used & chilled iron base lifters
on the new cast cam.
By using the old chilled iron lifters
he still had a hand grenade in the making
even if correct oil & break-in procedures
were followed to a tee.
