Have you checked the layshaft retainer plate end of the layshaft in the casing for vertical play?
Ive found on a few casings that have had some abuse that this hole goes out of round and the shaft floats up and down.
To check I clamped some bar stock across the block to box flange and used a mag' base DTI on the shaft to measure.

I already learned that used metro HLE gear sets can’t take the torque. Rebuilt that and put in the Minispares helical set, some updated drop gears, new layshaft and bearings. Not sure yet what’s caused this. I wasn’t giving it much (like 2psi under 4000rpm) because I’ve not mapped it enough yet.

Hypothesis from Guessworks is the retainer plate in the layshaft.
