Re: which are the best 400 castings?
dont get too caught up in casting numbers, imo.
the most important thing with them is little or no core shift, and the 2 bolts are preferred because the main web is more stout than the 4 bolts. the best bet with a factory block is a two bolt block with splayed 4 bolt caps, no core shift. after about 550 horse or so (yes many people have gone much more) i'd go with an aftermarket block.
unless a great factory std bore 400 falls in my lap (that would hafta hurt), my next motor will utilize a world or dart block.
