Looking at the Howards master list, I can find the current Hughes cams lobes there...... so there is no mystery as to what those are.
Looking the the Hughes site, their
STL6468BS3-8 cam(.414/.421 lobe lift)...... then look at the Howard’s master list....... the lobes are right there.
The mystery for me is still....... what lobes and from what supplier were the previous generation of Hughes cams ground from?
Like the HTL6468AS.
The Howard’s lobes are 28* major intensity....... so they're pretty fast.
The Comp MM lobes are actually a touch quicker(26* MI).
My “opinion” on the stories from Howard’s with regards to the Hughes cams is....... it’s politics.
They don’t want to just come out and say they can grind you the exact same cam you can get from Hughes........as a courtesy to Hughes.
