Hey, Harden. I totally enjoyed your post, it's great to start off the day with a good laugh! I was rolling on the ground after I read the part about the wrenches that don't fit, and the wonderful new space age metal, aluminum.
Congrats on keeping the Polara running for so long. That is a major accomplishment. I love good old V8 Americana too, but they have a way of turning back into the elements of which they are made.
Sorry I can't help with the missing at high RPMs. There is an amazing amount of knowledge and experience on this board, though, so you will get a lot of good info today from the members. I bet someone will advise you about the diagnostic computer codes our cars put out when there is a problem. Someone will probably also advise you about cleaning the MAF in the intake system.
Don't be alarmed if you also get some humor-challenged replies, too. It happens even on the best of forums.
