How is it a bow tie term if the fords have big blocks and small blocks too. Chevy's aren't the only ones with big blocks and small blocks. i don't get what you are saying.

Clevelands have the smallblock tranny pattern, and are normally refered to as smallblocks. The real question is, is a 351M/400 a big or small? They have the big tranny pattern, but a based on the cleveland block (only bigger
) How about 351Medium/400

Yes, Chevy’s aren’t the only ones but they were the first ones to be called smallblocks with the introduction of the diminutive 265 back in ’55 and it has stuck ever since. When the 396 came out in ’65, it naturally became known as the bigblock. There wasn’t any block in the middle to confuse things back then. I think Nathan has the right idea.

What I have read in the past is that the 351M/400 were never classified as small or big blocks. They were just V-8 engines. Just what I've read.

IF they are not classified as big blocks, how do you know what transmissions bolt up, a big block pattern or a small block pattern?

Justin- the 351 cleveland is a small block, it shares the same bore spacing as the 260, 289, 302 and 351W. It also has the same bell pattern. Some folks call it a big block only because they are ignorant. Yes this means that the 400 is also a small block, again, same bore spacing, 4.38 I think. Most 351M-400's have the same bell pattern as the 460 big block, but not all of them. Some of the 75-77 LTD's have a 351M or 400 with the same bell as the 289-302. All this really means is that you have to make sure you have the right stuff if you are swapping engines or something. DF

You cant consider a 351m/400 a smallblock because of its sheer weight and bellhousing
the 351 cleveland only has smallblock pattern/
But..
They are neither big nor small block.they are considered a 335 series or "cleveland block"

All I know is that when I went to the auto parts store and ordered the parts for a rebuild we had to look in the ford "big block" section of the catalog to find them. The parts suppliers tend to lump the 351c,351m,400 all in the same category, as they interchange some parts. I guess if it isn't a windsor block, it must be a big block.

the interchanging shouldnt matter...whoever wrote the parts book was ignorant..
theres Windsor parts that fit M's too.
like the crankshaft for instance.
there is 90degree small block and 385 series big block fords.
there is also FE block, y block, flatheads, and 335 series also known as the cleveland.
