360 vs 383

You can make power with any engine. 383 is no exception, I agree. And the 360 needs very, very little to go 12's. I've proven it. I'm there now, with 3.23 gears and the factory stock converter and a smaller cam than a stock 383 commando.
My personal preference against 360's doesn't mean I can't appreciate them. I built quite a few for other people. I just happened to be building engines in the 70's and have a stash of my favorite engines, and evidently may never need them. No 360's, they were sold years ago.
