Is there a short and long block 7.3 and what do i have?

Those are engine terms for when you buy a new or reman engine. Short block is an engine block assembled with the crank, rods, and pistons I think. A long block is an engine assembled from the oil pan to the heads. A short block you re use the heads off the old engine and a long block comes with the heads already on and all you need to do is install the accesories on the front of the engine like the water pump, A/C pump, ect...

i thought short block is just the bare block and long block has the pistions and stuff wo the heads.

Big block and small block are gas engine terms. If you want to get technical a small block is typically less than 360 cubic inches and a big block is larger than 360 cubic inches. a 7.3 liter is 445 cubic inches so by definition it would be a big blcok

A short block is a rotating assembly only and a long block comes complete minus excessories intake and injection accesories
