500 vs 512 from 400ci

Minimal experience here. Especially on high horsepower builds. But the 230 block does not guarantee thick cylinder walls.
I have one going into my car and one on the shelf. Kinda bummed at the cylinder thicknesses. Seems to average on the same minimal thicknesses as the later blocks. Maybe overall thickness may be greater?
So In my head the stroke combination which stresses the cylinder wall would get the vote.
I am surprised though how many thin spots are likely in a lot of high horse engines that are not known and never have issues.
My 230 block has 451 rotating assembly with Eddy heads so hope it is never an issue. Wish I went 470.
So stock block be sure to sonic check. Be prepared to add a couple sleeves. Could get closer to aftermarket block?
Getting hard to have several blocks to choose from and picking the best one. But my paranoia may be based on my lack of knowledge. I also have terrible luck. So it would take me a lot of blocks to have one that had nice cylinder walls.
