What exactly is the difference between a 4.7L V8 and a 5.3L V8?

Question

What exactly does Liter stand for, and what determines the numerical value or measurement such as 4.7 or 5.3?

Answer 1

It refers to the engine displacement - the amount of space each piston moves through inside the cylinders, multiplied by the number of cylinders.

The 5.3L V8 has more displacement, meaning that on each piston power stroke it will burn a higher volume of fuel, releasing more energy and therefore producing more power (all other things being equal).

By the way - is your handle "monkeybacon" a reference to Mockingbird by Walter Tevis?

Answer 2

4.7L and 5.3L refer to the size of the engine. The bigger the number, the more powerful the engine will be, but it will also likely get poorer gas mileage. A liter is a unit of volume like a quart, or gallon, but is a unit from the metric system. That being said, a liter is a little bit larger than a quart. You may have heard of engine sizes being expressed in cubic inches also - a 302 cubic inch engine is roughly the same as a 5 liter engine.

BOTTOM LINE: Get the bigger one.

Answer 3

Liter is simply a unit of measure. For example, look on a gallon of milk, it should have a measurement of 3.8 liters. But here in the U.S.A we are not used to measuring in liters, so we just go by the standard measurement, ounces, pints, quarts, gallons and so on. Either engine could be mearsured in gallons but, it would not be a very accurate measurement. The determination of the numerical value is how much liquid does each cylinder displace. The bigger the number the greater the displacement.

Answer 4

Engines used to be measured in cubic inch displacement in the U.S. and liters in almost all other countries. The U.S. finally changed to liters. A 5.3 is a bigger engine than a 4.7. A liter is about 61 cubic inches, so your 4.7 is a 286 cubic inch and the 5.3 is about 323 cubic inches. The liter itself is a metric unit of measurement.

Answer 5

A liter is basically a metric quart and the 4.7 or 5.3 is the total volume of all the cylinders combined. A 5.3L is also a 305 cu.in. motor in traditional terms.

Answer 6

Liter stand for the volumetric capacity of the cylinders. One 4.7L V8 means that each cylinder has a volume of 0.5875 liters or 35.8514 cubic inches.

coaching is stable, because of the fact it teaches you the right thank you to income, a thank you to discipline your techniques. information for a Christian is understanding the be conscious, understanding your God, His nature, His will, His outlook on issues. expertise is observing issues from God's attitude and putting them into action. information is super, yet too a great number of it could puff you up in case you do no longer counteract it with fruit of the Spirit. Ever comprehend a man or woman who's very knowledgeable, yet has no temperance and no love? Their information is virtually ineffective interior the long-term. yet expertise? you come across that and your soul shall stay, because of the fact once you come across expertise, you come across the way God Himself seems at a difficulty. Proverbs 3: by technique of expertise the Lord laid the earth’s foundations, by technique of information he set the heavens in place; by technique of his information the watery depths have been divided, and the clouds enable drop the dew.

Answer 8

A liter is 61 cubic inches so do the math and it will give you the displacement

Answer 9

There the same block one just has smaller pistons

4.8 Liter has 285 hp
5.3 Liter has 295 hp

Answer 10

Engine displacement.

Add up all the volume of what the eight cylinders would be at when they are at the bottom of their stroke and you get the liters of displacement.
