Explorer/Mounty short block vs. Aviator short block

Does anyone know what the differences are between the Explorer/Mountaineer short block vs the Aviator short block? Is it just the forged crank?

Welp, that thread did confirm my fears about my current Aviator engine. Same symptoms, i'm now petrified if my crank is shot. Will find out from the shop later.

Yup, I remember that thread. I had both heads rebuilt and one of the cams replaced in February due to the never ending misfire game which wound up being a failed cam which lead to low compression in one of the cylinders.. I've had it with this engine. I found a 2005 long block with 78K mi for 1700$ and I'm tempted to just pick that up and have them swap it in and just sell my old heads to make up a bit of the cost. I'm so frustrated.
