About 5 miles per gallon.
Seriously, Typically a big block is larger overall in width,height,etc. In some cases, the big blocks started out as engines for big trucks and industrial applications. These engines are bigger and heavier, but they are also sturdy with lots of torque. These engines tend to hold up to modifications pretty well since they have beefier lower ends and extra space between cylinder walls to dissipate heat.
A few examples of Chevrolet big blocks are the 348,396,427, and 454.
Examples of small blocks would be the 265,283,327,and 350.

Chevrolet made a 400 small block and a 396 big block,Ford made a 400 that is considered a small block and a 360 big block...my point is that cubic inches does not always determine if it is a big block or small.

Displacement. The small is smaller the big block is bigger. The real question is what classifies an engine as a small block or big block. That depends of the manufacturer mostly.

This is just a shot in the dark, but I'm thinking it might be size.
