Hemi or even a 440 is a much harder block to cast than a Chevy or Ford and if it is cast iron it makes it tougher. The Newest KB block that is out now has had a lot of revamping is the casting and modern upgrades to various parts of the block, such as oiling and other stuff. I heard the new team put 150K to make this block much better. The new KB is a sweet piece and a lot of racers in the over 1000HP motor will have no trouble buying it. It sure would be nice to have a new Iron Hemi Block but this story is the same every 3 or 4 years and this is one reason people like FHO had to step up and have blocks made because there just were not any around iron or aluminum.
