My last 427 was a standard bore original iron block with 1st generation Shelby aluminum heads that did not flow much better than the originals. It was a stock 3.78 stroke 12:1 compression
1-750 cfm 4bbl with a bigger cam than we are speaking of and we made 581hp. I was 427 cubes. The motor in question by size alone should have the ability to surpass the 581 or at least come close. Keith kraft seems to do it all day long.
