Machine shop terminology.....
Both engine are the same size......in machine shop terminology it usually means......
Short block..... is the engine block, pistons, crank and cam shaft and timing gear with cover....... nothing else is included....
Long block...... same as above BUT it includes the installed head(s) and valve train and usually includes the valve cover and oil pan, oil pump...... DOES NOT INCLUDE intake/exhaust manifold , carburator, water pump, distributor, generator, pulleys,
A full "drop in" would be an engine that has all the accessories attached ready to be bolted in and run.......
Good luck
Cheers
