Take a look at a bare 400 block look at the space between the cylinders and you will see it is much less than the space between the cylinders on say a 350 block. Then you put a couple of extra holes in the block for the (siamesesd cylinders) not to mention the extra holes in the head gaskets and you can clealy see why they are more prone to blowing out.
