67 Cuda: disappointing dyno numbers, need some advice!

and your sources are good. :) Big block version in '90 catalog but the small block version was gone.

My source for that was from someone who said they’d used that cam before(who I had faith in them knowing what they had)......... and that story was being stored in the aging gray matter.
If the 455/455 SB cam was gone by 1990...... it doesn’t sound like it fits the build timeline of 1995(unless it was sitting on someone’s shelf for a while).
