1. Yes
2. No

Hard as it is to believe, muscle cars can actually be fuel efficient. There were even some pony cars from the '60s and '70s that used smaller V8 engines.

1. Horsepower
   Torque
2. Both

The large gas-guzzlers provide amazing power and torque. Unfortunately, you don't get these same benefits from the smaller engines, but you're still getting a great deal of power.

1. Ford Mustang
   Chevy Impala
2. Dodge Crescent

The Ford Mustang is one of the best small-engine muscle cars ever sold. This was fueled by Ford's popular 289 engine.

1. Chevy 350
   Dodge Magnum 440
2. Dodge HEMI
   All of the above

All of these engines are popular in muscle cars. The Chevy 350 is actually one of the most popular engines ever built.

1. T78
   B34
2. L48

The Chevy 350 L48 is the most popular engine for muscle cars. This spectacular engine has been around since the 1960s.

1. 4-9
   10-17
2. 35-40

A muscle car engine with 500 horsepower is only going to get about 10-17 miles per gallon. Now, that's what you call a gas guzzler!

1. Dodge Charger
   Dodge Challenger
2. Plymouth Road
   All of the above

All three of these cars easily use this muscle engine. They also work great with a Dodge Magnum 440.

1. 1 to 2
   6 to 10
2. 10 to 12

Believe it or not, some muscle engines only get 6 to 10 MPG. When you install this kind of engine, you can only call it a labor of love.

1. Box engine
   Crate engine
2. Semi-engine

The crate engine is an affordable way to boost your horsepower. It's basically an all-in-one engine with naturally aspirated horsepower and less trouble.

1. Yes
2. No

With a muscle car, you can't go out and select any kind of engine. The engine that you choose is going to depend upon the size of your car and the way the car connects to the engine.

1. V6
   V8
2. V10

The massive V10 fits beautifully into a Dodge Viper. But it just goes to show, you need different engines for different muscle cars. The Ford Mustang can only handle a V6.

1. Yes
2. No

You can actually do a lot of work under the hood to make a muscle car handle a larger engine than it's designed for. That being said, sometimes it's easier to take a smaller engine with a lot of power, or go for a crate engine.

1. Horsepower
   Car design
2. Weather

The horsepower is going to determine a lot of things for your muscle car. The horsepower of your engine will greatly affect your transmission, gears, fuel system, tire size and so much more.

1. True
2. False

Remember these words, gentlemen. The more displacement you have, the more power you get out of your car.

1. $100
   $1,000 - $2,000
2. $10,000

If you're replacing your old muscle engine and installing a new one, you can expect to pay at least a couple grand. This is going to depend upon the make and model of your vehicle.

1. Formula One cars
   Sports Cars
2. Their own weight and size

Considering their weight and size, muscle cars are the most powerful vehicles on the road. The engine is the heart and soul of the muscle car.

1. Tires
   Large body
2. Large engine

The very definition of a muscle car is an over-sized engine in a small to mid-sized car. This gives you a very powerful vehicle that accelerates quickly.

1. '40s
   '50s
2. '60s

Muscle cars came about in the early '50s. This coincided with a trend in drag racing in the US.

1. Yes
2. No

There are new models of muscle cars still being built today. But it was very specific Ford muscle engines that started it all.

1. V4s
   V6s
2. V8s

HEMIs are a series of different V8 engines. There are 8 separate valves for internal combustion, and these were the largest engines that a muscle car could handle for quite some time.

1. Longitudinal
   Octaganol
2. Hemispherical

The HEMI is defined by its design. It's hemispherical in shape. This shape allows for repositioning of the valves in the engine chamber allowing for more space.

1. HEMI
2. Non-HEMI

Because of their design and layout, HEMIs are more powerful than non-HEMIs. That's why muscle car owners swear by them.

1. Rockets
2. Muscle cars

Okay, that was an easy one. But rocket engines were the first and most popular of the initial muscle car engines.

1. A V6
   A 4-stroke engine
2. A rocket engine

In 1949, the Pontiac GTO was the first to be powered by a rocket engine. At the time, the muscle car rocket engines were the most powerful on the market.

1. 100 horsepower
   110 horsepower
2. 150 horsepower

Early rocket engines were capable of well over 150 horsepower. That was a seriously high amount of power for the time that they were created.

1. Engines from the manufacturer
2. Non-manufacturer engines

Most muscle cars today use engines from a separate manufacturer. These crate engines come from third-party developers.

1. Classic music
   Sound of the engine
2. Sound of birds chirping

Let's be honest, the sound that your engine makes is a great part of the fun. The more high-end your exhaust system, the better the sound.

1. A V8
   Wings
2. Muscle car sound

Let us drive this point home, if it doesn't have a muscle car sound, then it's not a muscle car. Yes, this is opinion, but everyone you ask will agree.

1. Isn't clean
   Makes bad sounds
2. Is being admired

When your engine makes the wrong sounds, it's like the clouds have taken the sun hostage. When your high-performance​ engine sounds sick, you become sick as well.

1. Rod going bad
   Failed motor mounts
2. Heads need replacement​
   All of the above

All of the above predicaments could cause your engine to create bad sounds. If your engine is like a set of lungs, when things go wrong, it sounds like it's gasping for air.

1. Change air filters
   Change oil
2. Change transmission fluid
   All of the above

Well, that was an easy one. If you want to keep your high-performance engine sounding great, you have to make sure to maintain the engine. Treat it lovingly, and it will love you back.

1. 250
   300
2. 427

The famous 427 Chevy displaces 427 inches and still produces 430 horsepower. Now, that's a great muscle car engine.

1. '40s
   '60s
2. '80s

The famous Chevy 409 was built from 1961 to 1965. This first generation was named the W series by General Motors.

1. '40s
   '50s
2. '70s

The 413 CID Big Block was built in the late '50s. Chrysler lovingly named it the B series wedge engine.

1. General Motors
   Buick
2. Mopar

Mopar made the 426 HEMI. This is one of Mopar's most famous V8s. It was built from 1964 till 1971.
