That's for the whole 'package', who's contents are listed at

Is this much more than the standard Lycoming/Continental?

Also, the V-220 is supposed to get .42 lbs/hp-hour. How does
this compare to the standard aircraft engines?

-Much Thanks

Lycoming claims .435 while burning 9.8 gallons/hour with a fixed pitch
prop while running the engine at 75% power. This is for a 180 hp
engine.

The Deltahawk diesel claims a BSFC of .38 while running at 75% power.

Some of the larger radial engines used to be able to reduce the BSFC
down to under .4 by extreme leaning.

Most auto engines, even the modern ones with computerized everything
still run at a BSFC of .50 or higher. That's on the street. Put that
same engine in an airplane and lean the mixture for max range and it's
likely the BSFC will be lower.

To get most of this information I used Google, and typed in "BSFC
Lycoming".
