<edit>
Engine output with 40% efficiency out of the engine would still put 30-40% out the tailpipe and 20-30% radiated from the bloc itself.
If you can recover even 20% of either(or both!) you gain a 50% fuel economy boost. Even if ICE gets to 50%, you could still recover 25% of the lost heat and gain a 50% boost in economy and still be well under what stirling engines are capable of today.
