Very interesting, but I'm afraid it would make me a die-hard Chevy fan if I read it all the way thru. Ford surely strayed from the basic principle of mass production: interchangeability....
Most of its probably right on, but my immediate reaction is one of caution when an author calls the 400 an "M". With all due repect to fathack, I'm sorry but in my book it just ain't so.
the hamb doesn't remember my sign on, but then again it's been a couple years. And of course I can't remember the password, lol. I just wanted to ask about the D5OP bell for the C4, and it's application. It's good info for the not-so-Ford-diehards.

I seem to recall that the 'M' motor and the 400 are the same, can someone clarify that for all of us?

The 351M is a destroked 400, so yes they are the same except for terminology. As far as I have been able to determine Ford only referred to the 400 as their 400. A few years later they developed the 351M as a mid-sized truck engine from a destroked 400 and it was smogged from the get go.
Then in a couple of service bulletins Ford referred to the 'M' engines and the terminology has been screwed up ever since.
I was old enough to be driving when the 400 first came out alone. There was no M about it. It made very respectable HP until it was smogged in '72.
Look at the valve cover sticker of every one of these engines and you'll see they read 351M/400.
So it's semantics and guys will keep arguing about that M.
