It's all bullshit. It's just "showin off" what can be done to an engine block. The small block's oiling system is WELL ahead if it's time in totally stock condition. It's all smoke and mirrors.
No smoke and mirrors if you want to shift at 8500. It’s fine if you want to keep it well below that. You still need full groove bearings, you still need to control the leaks, and you still need to get the pick up tube as big as you can, and with a center sump pan that’s about impossible.
