Strange cam specs

Yeah, so how could anybody really "miss"?
That’s what I was thinking.

I mean, if you were only checking the C/L of the lobe, then I can see it.
But if you’re checking the open/close points…….. it would be obvious if you were on the wrong lobe.

I’ll slip in an anecdotal story here……
A few years ago a customer brought in an Olds 350 that he wasn’t happy with.
It had been rebuilt a few years before, but didn’t have any grunt at all.
The customer wanted a different cam, so it got a small XE put in it.
It had a Comp 260H which should have been fine, but he wanted something else.
I don’t recall exactly how it went down, but during the degreeing process the builder determined the 260H had been installed a bunch retarded.
They(must have) degreed it off the exhaust lobe…….. because on an Olds, the end cylinders have the in/ex valves reversed from the more traditional layout.
So the cam was set up at 106…….. using the lobe that would be where the intake lobe is on a SBM.
But that’s an exhaust lobe on the Olds.
Intake was in at 114. Oops.

Needless to say, with the new even shorter duration XE cam…….. properly degreed in to 106……. The low end power was greatly improved.
A burnout was now possible.
