You won’t see a bunch out there. Why would you? Why should someone do all the work and/or pay for it and post it?
It all matters. It’s all interrelated. You might find 20, maybe 30 hp and not spend a cent more IF you don’t ignore important **** like rod ratio and how it affects cam timing, how cam timing affects compression ratio and so on.
You can think and believe whatever you want, but saying geometry doesn’t matter is just silly. Or ignorant.
