I'm currently having Loynings Engine Service(winning formula atlantic engine builder) build me a bottom end. I'm using the smaller crank because it is SUBSTANTIALLY lighhter....

What is common is if it isn't properly balanced the journals marked begin an oscillation because they are not the same as the counter weight on the other side of the journal. This oscillation can be eliminated with balance, and hardening(shotpeen the crank

Using a newer block that is a bit stouter never hurts either

early block on the bottom(upsidedown), later block on top

You can | Sad
