Have you actually seen a 427 stroker kit for our cars? I dont think I have, and it sounds impossible. That would add 140+ cubes which is a 50% gain over the stock block size.
No such thing, about the biggest Ive seen in the modular 4.6L family is a 5.3L Boss block from MMR. Oh and I see you used the plural "cams" implying a OHC motor.... which a 427 is not.
