The size of the block.
Usually, .12- .18 engines are small blocks and .21- .24 are big blocks...
There are some exceptions though...

Big block engines don't fit in the Nitro Rustler w/o modifiying things... You will need to buy new engine mounts, and drill holes for them.
Big block .15s are also used for on-road racing.
I don't know of any places that sell them... (stormer, horizon, and tower don't)
