My take on the oiling system crossover tube for the small block

No, I dont think I'm missing the point at all. I've never had a sbm turn enough rpm with a hydraulic cam, to need any "fixes" to the oiling system. And I have quite a bit of experience with oval track mopars, and sustained rpm.

Then your motor that spun the bearings had a solid cam?
Sorry about your motor not wanting to rev. You might want to look into that.
