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

.
Without being able to see your block it's a coulda shoulda woulda deal.

Are you missing the point of the crossover is used on a motor using hydraulic lifters?

Solid lifters you either tube the passenger side or bush the lifter bores.
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.
