Long block is an automotive term for an engine sub-assembly that consists of the assembled block, crankshaft, cylinder head,camshaft (usually), and valve train A long block does not include fuel system, electrical, intake, and exhaust components, as well as other components.
Short block is an automotive term for an engine sub-assembly. A short block is the portion of the cylinder block below the head gasket but above the oil pan. An in-block cam engine includes the camshaft, timing gear, and any balance shafts. Overhead cam engines don't include those parts.
With that engine from AB, you would need to have your heads rebuilt and reuse your intake, oil pan and all accessories.
