Hypothetical 318 Builds

So.. i'm curious.. is the oiling as bad in a small block like some people make it seem? I had a lot of friends spin bearings in small blocks when i was a kid.. but prolly stupid driving..

I see the mods like the crossover in the lifter valley and tubing the oil passages and **** and wonder if it's needed...
The crank is the first to get oil. It sounds like the rod bearings need more. THey usually reduce oil to the top side because it isn't need there as much. IF you rpm a Mopar you need some improvements. 6-8000 rpm. All engines do.
