Shortblock= Everything below the head gasket. Block, crank, oil pan, pistons, rods, etc.
Longblock= Complete motor minus trans (block, head, intake manifold, exhaust manifold) I purchased my B16A longblock from hondamotorsonline (now hmotorsonline), and it came w/ the intake manifold. But, it was missing the distributor and the lower half of the exhaust manifold.
