Just in case anyone was wondering, because I did......Displacement alone doesn't classify an engine as a "small block" or a "big block"
Here are the best definitions I have been able to come up with from
http://www.chevytrucks.org/tech/block.htm
Just some good general knowledge.....
Quote:
Short Block: An engine WITHOUT the head(s). Usually includes the crankshaft, camshaft, and pistons.
Long Block: An engine WITH the head(s). Usually does not include the oil pan, valve covers, and manifolds.
Small Block: The smaller of a manufacturers two series of engines. In the case of Chevy, the small block includes the 262, 265, 267, 283, 302, 305, 307, 327, 350, and 400.
Big Block: The larger of a manufacturers two series of engines. In the case of Chevy, the 366, 396, 402, 427, and 454.
Notice the overlap of small and big block displacements. Note also that a small block can be a long block. The terms define different characteristics of the engine.

I also have read that it has to do with the actual spacing of the cylinders. The LS7 is still considered a small block engine and it is a 427ci
