Me, I've daydreamed about getting hold of one of the Argentinian big "906" Slant-6 blocks that'll support a bigger bore than the regular items, and bore it to 3.745". That would yield 273.35 cubic inches, then I'd put a Hyper-Pak on it and go around telling people—truthfully—that it's got a 273-4bbl.
