These are useful:
Power / fuel economy
Power / physical external size
Power / engine weight
Who cares if you make a ton of power our of a relatively small internal displacement if the fuel economy sucks, engine is heavy, engine is physically huge, etc?
Let's look at the MY18 Mustang's 5.0 with 460hp. It gets worse fuel economy, not lighter, and external size is larger than the LT1.
Tell me: What's that smaller internal displacement buying me, from an engineering standpoint?
Regarding being "far behind in efficiency": Please list off other 455hp/455lb-ft engines with better fuel economy ratings than the Corvette and Camaro.

To sum up, I believe the torque curve is a much better measure of efficiency than HP/Liter. Torque is the measure of how hard the engine has to work to achieve the result, and the LT1 doesn't have to work nearly as hard as the other engines mentioned.
