stock or hv oil pump

I think some guys are over thinking this. An LA small block will take a lot of horsepower with almost zero work. I don’t think you really want to go drilling holes in what is probably the weakest part of the block. Not trying to be a smart *** but hot air doesn’t cool very well.
My dad worked for a chrysler/dodge dealer from 1963-1979. He worked on 340 6 packs hemis 340 demons, etc. He never saw any have issues with oiling. All were stock and run hard especially the 340's. He did have some come in that blew a rod but he says it was overreved or just plain abuse!
