Displacement
Certainly they're not burning 5.0L per "rotation(?)"... Is it a specific measurement that doesn't necessarily mean anything other than how much liquid you could put into it?

total volume of the cylinders.

when the piston goes down, it sucks an air and fuel mixture into the cylinder. when the piston goes up, it compresses the mixture. at the top, when the mixture is most compressed, the spark plug ignites the compressed gasses, which expand quickly, driving the piston back down and thereby turning the crankshaft and sending power to the wheels. rinse and repeat.
the bigger the cylinder, the more fuel and air is used, and the more power is created. a gallon of gas contains more energy than a thimble of gas.

Larger piston area and/or stroke = more fuel/air in cylinder = bigger 'SPLOSION = VROOM

Ok. That makes sense.
One thing...
So the "cylinder" is rated/measured at "5.7L"... Does that mean they're pumping in 5.7 liters per "splosion"?
Seems like you'd go through a tank of gas after like a dozen turns of the crank?

No replacement for displacement.
All things being equal, a larger engine makes more HP.

5.0L is 305 c.i., which is a very nice engine. My mom's '78 Pontiac had one of those and it ran like a scalded cat.

It's the amount of oil the wobble shaft requires.

Cmon...You know things aren't always equal....

Holy shite... I bet the MPG on that is through the roof..............

I was gonna show Tchefuncte Tiger what a modern 5.0 supercharged engine felt like, but I'm afraid it would snap his neck.

In one cycle of the engine, 5.0L of air will be sucked in and ignited. Or the total volume of all the cylinders. So a 5.0L V8 will have 8 cylinders that are each 0.625L

That used to be the case. Nowadays with all the super and turbochargers smaller engines are putting out more power

That 5.7 is the total of all cylinders. And no, that doesn't mean the whole thing gets filled with fuel. It gets a tiny bit of a fuel and the rest is filled with air. You can't have an explosion without air. And the more cool air you stuff in a cylinder, the bigger the explosion. That's where turbo and supercharges come in to play

What you need is a 12.0 L to help out all the oil field baws

Optimum air fuel ratio for a naturally aspirated motor is 14.7 parts air to 1 part gasoline.
The cylinder does not fill full of liquid gasoline on each stroke.
Trust me. I'm a MPG expert.

That was the keystone statement in this whole thread.
