that is basically the heap paradox. lets say you have a million grains of sand. compared to 5 grains that is a heap. if you continuously take one grain away, when does that pile of one million become a "non-heap" ?it's a matter of opinion, i believe.
"The v8 350 is a small block Chevrolet motor.....................it became a big block at 396cubic inches......so anything smaller is a "small" block" this is a little misleading. a 350 is indeed a small block. a 396 is indeed a big block. but you can have a small block that is (internally..cubic inch wise) actually larger than a big block. for example GM made a 400 cubic inch small block. internally it is a larger engine than a 396, but the outer dimensions of the 396 are larger than the 400 small block. and the external dimensions and cylinder head design are what make a small block a small block, and a big block a big block. a small block engine simply has a physically smaller block...a big block is called a big block because it's block is bigger than that of a small block.
Small block
It is a small block
A 350 is a small block and all the engine parts are small. The 454 is a big block and everything is big. Nothing will interchange.
Big block
Pontiac uses same block no small or big, Chevy describes their engines small or big
That would be a small block.
It is a small block.
BIG BLOCK OR SMALL BLOCK DOES NOT DEPEND ON CUBIC INCHES . IT IS THE DESIGN OF THE BLOCK ITS SELF.
Windsor 351, is a small block. 351 Cleveland, is a big block. The 351M, stands for "modified" and is a windsor (small) block, with Cleveland (big block) heads.
It is a "windsor" (small block) with Cleveland heads (big block).
The 350 engine is a small block, not a big block.
