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

The small block Olds has many of the same oiling issues that the Mopar has. I learned early on in those engines to match the #5 main cap with the oil gallery, slot the mains to match the bearings... even open up the oil return passages in the head to prevent oil from stagnating on top of the head.

As someone who has a vested interest in keeping a SBM alive at 7,200 rpms, and has an engine that tossed the #2 rod causing fatal damage, I'm trying to keep an open mind.

I had several discussion with Charles Sanborn about his oiling mods... seemed to make sense.
