Where to degree this cam ?

IMHO the cam was ground keyed off that 8 degrees. And the intake was ground a little early. So the LSA closed up a bit.

For a flat tappet....a lifter diameter change will change lift angles equally and in opposite directions on both ramps of each lobe, so should not change the ICL and ECL or LSA or the install angle on the spockets. But I missed earlier that this is a roller; the comment on the diameter was for thinking it was a flat tappet.
