The Owner's Manual says 7 quarts, but it's wrong.

That's correct; on the FB engine one complete bank fires, then the other fires.

Lycoming Model FC V-8 (supercharged)

The Owner's Manual says 7 quarts, but it's wrong.

Lycoming's dynomometer charts show these horsepower and torque ranges for production engines. For some reason Auburn always advertised 170bhp, which was the output of the earliest test engines before cam grind and timing were tweaked.
