Stock 440 blocks are questionable over 600HP in general, stock hemi blocks were good to almost 2000HP on fuel in the 70 era. So yeah when you can buy a new Hemi block (which are even superior to the 1970 block) in the $2500 range that has never been stressed in anyway it just doesn't make any sense whatsoever to use a 440 block. I have never been a fan of doing funky welding and machining to cast iron when there's a better way.
