The 403 guys on ROP generally run a main cap girdle to help hold the windowed main block together. J&S and others have girdles. I suspect the DX block is overkill and very heavy, but a 350 block sleeved might be best. Of course, a block with .921 lifters would help with a radical profile cam vs. the .842" lifter blocks.
