In the later years, Pontiac had some wide LSA cams, 116-118 or so, and suspect it was due to plugged up exhausts with cats, but there was not much trade off on power without other mods, so...

Some of the earlier Crane cams used 114-116 LSAs and were good performers, but sure there were specific reasons for those numbers.

On what is basically a 327, with tall intake ports, I suspect there was some concern about intake velocity, and sure they did a ton of testing. (for all-around performance).

As for documentation, engineers are pretty terrible at docs, and generally dread doing them. Most are rushed, lack grammar, and things (tech/assembly) change along the way. Discernment is always advised.

Nice catch by the way, and the discovery & sharing will live forever on the internet.
