You are welcome to your opinion.
None of the "old" 427 blocks has won Hot Rod's Drag Week. Jay Brown has won it with a Genesis 427 though. He was close to winning it a second time last year and would have if there had been decent Cammer 427 rocker arms available.
No speculating here. The new side oiler blocks are made from better materials and the design has been improved upon. Again, referencing Pond, Genesis, or Shelby blocks, all of which are easily superior in a multitude of ways to any original side oiler block.
These new 427 blocks are not going to make any different amount of power if built identically to an original. A good rebuilt original is going to be just as reliable at the horsepower levels seen at Nascar back then or at Le Mans, say 550 horsepower. I doubt that anyone is going to build a pair of engines to the same specs just to satisfy posers who don't understand the question is already answered.
