Why are people so one-track? "Smaller displacement = better fuel economy" is not true. Power to displacement ratio means nothing in unrelated engine formulas. Power to engine weight counts more. How about power to external engine dimension? An OHC Ford modular V8 is externally larger and heavier than an LS-series Gen III/IV. High HP is made relative to cylinder displacement @ higher RPM through greater top-end volumetric efficiency.
The 3-4 valves/cylinder design allows for better airflow w/ less turbulence @ high RPM. Greater airflow requires more fuel during the combustion cycle which likely = less fuel efficiency. All this high RPM HP typically comes at the sacrifice of low RPM Torque (VVT can mitigate this to some extent). Forget peak HP/Torque numbers for a second. They are the playground of the marketing division. Look at the Torque curves of both engines and then tell me which is more powerful.
Also, what mythical Ford has a 400HP 5.0L V8? Don't mention a future product or a crate motor. Also, name a 400HP V8 that gets better fuel economy than the LS3.
Also, look into a spell checker.
