Bitter learning curve. Absolutely DONE with carburetors!!!
Wow, that is all good news and that gesture on Rick's part is awesome! Sounds like you are coming out of the woods on this, and maybe you did a fine job after all. If you ever do go to FI, you have a sound base to work from.
BTW, I would not make the same conclusion on the oil mod lowering the pressure all that much unless you made that hole waaaaay to big. That point is on the far 'end of the line' of the oiling system. But your PSI at 3k is sure good.
