Maybe I'm a doofus (ok, perhaps more than maybe), but I always thought that it was called "modified" because that's exactly what it was....a destroked, or "modified" 400 of 351 cubic inches. I thought the 351M came after the 400, so it stood to reason that they just modified a 400 for a newly configured plant. They probably put the "M" on the end because there were already 351C's and 351W's, so they needed the M as a designator to differentiate it from the others. This is also why I think people who say 400M are silly, as there were no other 400's to differentiate from, so there is no need for a letter designator. It's just 400. Anyway, that's just my oddball logic.
. Yes, you obviously copied this posting from my posting further above... (except your first sentence... LOL!)
. Not mentioning any names, but now we know who doesn't read the entire previous thread before posting... (wait, that contradicts what I just said...)
. Wouldn't have to do much 'configuring' to a plant, since a 351M differs from a 400 just by crank and pistons and sticker on valve cover... send those tall blocks down the line and drop in whichever parts for the desired engine size...

No, I "obviously" didn't copy your post, as you posted it in the form of a question, and regardless of a 351M only having a crank and pistons being the difference from a 400, it is still a different configuration. Since, however, you decided to point out what you believe about my reading habits while slathering on a thick layer of condescension, I've learned that you're kind of a tool. Bravo.
