we talking "everything" as in a complete engine? Or are we talking about "everything" as in just the long block?

those are two vastly different things.

"everything" usually means, at minimum, the complete engine, and all the accessories. It can include the harness and ecu. But that is usually labeled as a "swap"
A longblock is just from the valve cover, down the the oil pan. No accessories, no manifolds, none of that.


.... just sayin
