1. It refers to the shape of the design
   It refers to Heavy Machinery
2. Based on the creator, John Hemi

The name HEMI refers to the shape of the cylinder heads. They have a hemispherical design.

1. Porsche
   Volkswagen
2. Chrysler

It was a Chrysler that was the first to have a HEMI. This was in 1951, and it was a new line of V-8 engines.

1. 150
   250
2. 350

A 5.7 HEMI has 350 horsepower. There is one horsepower per cubic inch.

Chrysler has built three different HEMI engines. The first one was called the Chrysler FirePower Engine.

1. Yes
   Yes, but people build them on their own
2. No

No, Chrysler is not the only manufacturer of the HEMI. Many other auto manufacturers have mimicked the design.

1. Dodge
   Continental
2. Chrysler

Chrysler trademarked the name HEMI. Before that, many others had manufactured the engine, but Chrysler had dibs on the name.

A HEMI engine can only have 2 valves. These valves are quite large, and they must be heavier than those in a multi-valve engine.

1. The shape of the cylinder heads
   The shape of the valves
2. The shape of the chamber in general

It's the cylinder heads which give the HEMI its name. They're hemispherical in design and shape.

1. A flat surface
   The thick peel of an orange
2. A pillow

The combustion chamber resembles the thick peel of an orange. That is because the piston crown is domed and protruding.

1. Point in different directions
   Point towards one another
2. Don't exist

In the HEMI, the intake and exhaust valves point in different directions. That means that it needs a large, wide cylinder head.

1. The engine is so wide
   The engine is so tiny
2. The engine is picky about what car it goes in

A HEMI engine is incredibly wide. That's why there are only so many cars that it can be installed in.

1. Super Rockstar Head
   Ultimate Power Head
2. Double Rocker Head

Chrysler referred to it as the Double Rocker Head in the 1950s. This was in reference to the complexity of the new engine.

1. Civil War
   World War I
2. World War II

The first experimental HEMI was produced during World War II. It was for the Republic P-47 Thunderbolt fighter aircraft.

1. Pontiac
   Continental
2. Dodge

Chrysler and Continental actually built a HEMI for a World War II tank. It was called the M47 Patton tank.

1. FirePower
   FireDome
2. RedRam
   All of the above

These were all names for HEMIs. They were from Chrysler, DeSoto and Dodge.

1. 1949-1951
   1951-1958
2. 1955-1960

1951-1958 is the period that is known for the first generation HEMIs. You can tell it's a first generation by the rear-mounted distributor.

1. The flat head T engine
   The wedge-head B engine
2. The notch head Q engine

I hope you got that right:) The HEMI was abandoned in the '60s for the wedge-head B engine. This was a temporary abandonment.

1. 1:1
   1:2
2. 1:3

The bore/stroke ratio on an oversquare engine is 1:1. The HEMI is known to be an oversquare engine.

1. 1985
   1970
2. 1964

The HEMI enjoyed a revival in 1964. For about six years, it went out of style, but came back!

1. 1951
   1958
2. 1964

A HEMI finally got its name as a HEMI in 1964. This was when it made a reappearance on the market.

1. Dog power
   Elephant engine
2. The cyclone

The 426 HEMI was massive in size and power. That's why it was referred to as the elephant engine.

1. NASA
   A dirt bike
2. NASCAR

The 426 HEMI was actually built for NASCAR racing. It was used in a racing Plymouth Belvedere.

1. Boats
   Drag racing
2. Police vehicles

The 426 HEMI was used in drag racing. It could stroke to displacements that no other engine of the time could achieve.

1. Taller
   Wider
2. Flatter

Today's HEMIs, known as third-generation, have flatter cylinder heads. They're also far more complex.

1. Are more hemispherical
   Are larger
2. Not truly hemispherical

Todays HEMIs are not truly hemispherical in shape. But we're still glad that they kept the name!

1. 1990
   1995
2. 2003

The 5.7 L HEMI was released in 2003. They were installed in Dodge Ram trucks, 1500, 2500 and 3500.

1. Muscle cars
   ATVs
2. Submarines

HEMIs and muscle cars go together like peas and carrots. The 426 HEMI is the design that is used.

1. Jaguar
   Mitsubishi
2. Lincoln

Jaguar invented the 6-cylinder HEMI, before Chrysler got their hands on it. Harry Westlake developed it in 1948.

1. Pitiful
   Average
2. Amazing

When Chrysler introduced the HEMI, 180 horsepower was pretty phenomenal. It doesn't seem like much now.

1. 250 horsepower
   350 horsepower
2. 425 horsepower

The legendary 426 HEMI produced 425 horsepower. Wait. Why didn't they call it the 425? Such a mystery.

1. Cylinders
   Cyclones
2. Combustion chamber

The 1951 HEMI got its power from the combustion chamber. It was tremendously efficient for its time.

1. Under the combustion chamber
   Over the combustion chamber
2. To the side of the combustion chamber

The HEMI is known for having the spark plug above the combustion chamber, in most cases. The valves open on opposite sides of the chamber.

1. There is less surface area
   There is more surface area
2. It's actually not superior at all

The HEMI has less surface area, and that means less heat loss. With that, you're able to attain more pressure and power.

1. Small and streamlined
   Large
2. Flat

The HEMI design allows for large valves. That means that you can get more air pouring through the engine.

1. Four valves per cylinder
   A large combustion chamber
2. Increased power

The HEMI can never have four valves per cylinder. That's why its use is limited today.
