When I ask questions, I invite the answers, as long as those answers have a "why" attached to them. I'm here to learn, not be told an answer with no reasoning. That's backyard mechanic regurgitation. You have to learn to separate "this is how I've always done it" with the valid reasons why something does or doesn't work. This might explain to others why they give advice and I ignore it until I research further
Here’s a coupla things that I think you need to know.
Up until about 20 yrs ago there wasn’t the the technology to measure & model & compute the things that are here today.
Engine builders would dream up stuff, make it & test. Usually the results sucked lol
Occasionally something would show some positive results. There was no accepted reasoning as to why it worked but it opened a small crack in the door of progression. More testing may or may not show you why but it was there. More innovation & testing would show trends. More testing. More failures but occasionally a small improvement would arrive.
Very smart men could not prove why but it wasn’t really so important as more failures than successes would litter the discussion & you’d get paralysis by analysis. We just kept moving in a certain direction.
Thousands & thousands of race winning, championship winning, record setting engines were built with maybe 25% of the knowledge thats present today.
What was “secret squirrel “ shit was actually unexplainable but nobody would admit it. EGO & all that showmanship shit. Lol
You have access to todays science & even with all of it, nobody can scientifically prove that one way is better than the other. I think the newer science spent most of its early times trying to figure out why accepted results were what they were, sort of backing into results.
If it was as easy as you seem to expect, there would be one book with all of the answers & everybody would do it exactly the same way but NOPE!
Why do you think that all of the big hitters are ALWAYS testing testing testing, spending untold time & money to find 3 more HP or another .005.
There is no accepted answer to any of this because there is someone, somewhere hauling ass with damn near everything that the “experts” say is wrong. Instead of trying to figure out why it worked, most will accuse that guy of lying or cheating & dismiss a learning opportunity.
Take this for what it’s worth to you as I’m just trying to help you learn how to learn.
. To be honest, I was under the impression that you just wanted to get this thing together, you know, dot to dot
