Is it a Ford Engine or a Chevy Engine?

Produced in the U.S. for a period of almost 30 years, starting in1962, the third-generation straight-six engine was available in a number of displacements with the smallest a 3.2-liter and the largest a 4.8-liter. Chevy stopped using this water-cooled power plant in 1988; the engine was produced in Brazil from 1964 until 2001.

The Flathead V8 was a revelation by Ford in 1932. Quite simply put, at the time, there was nothing similar to it out there. Most importantly, it was cheap, which made it more accessible to people struggling through the Great Depression. It's often used by hot rodders today.

Certainly something a little different, the Voltec is the powerplant behind the Chevrolet Volt. The first generation consisted of an AC motor with a 1.4-liter liquid-cooled inline-four engine. The second generation had a 1.5-liter inline-four engine coupled with an upgraded electric motor.

This 60-degree V4 engine was first used by Ford in Germany in 1962 to power the Taunus, as well as the German versions of the Consul, Capri and Transit. It was available in a number of sizes, from a 1.2 -to a 1.9-liter engine, as was available until 1981.

This engine, a version of Chevy's famous 427 was installed in a legendary model of the Chevrolet Camaro, the Z28. This particular engine was a 7.0-liter V8 that could output 430 horsepower and 450 foot-pounds of torque.

The LT5 was the powerplant exclusively for the Chevrolet Corvette ZR1, produced from 1990 through 1995. This 5.7-liter engine produced more than 450 horsepower in its second generation.

This behemoth, found in the Ford F-150 Lightning, produces a massive 360 horsepower and 440 foot-pounds of torque! Tuners even managed to get more out of it, making the Lightning the performance truck to have at the turn of the new millennium.

Certainly not the most powerful but one of the most important engines ever made. Why? Well this Ford Inline-four drove possible the most significant car in auto history — the Model T. The 2.9-liter engine could only output 20 horsepower, but it was enough to get the job done from 1908 through 1941.

Made from aluminum, this 427 cubic inch engine was 100 pounds lighter than other big block V8s. This particular ZL1 big-block engine was put in a Corvette and, as a $4,718 extra, doubled the price of the vehicle.

The Kent engine, a small straight-four-cylinder motor, was first released in 1959 and has powered a number of famous Ford's European models, including the Cortina, Prefect, Corsair and Capri. The third and final version of the Kent engine was used up until 2002.

The Chevrolet Small-Block V8 was first released for the 1955 model year and by 2011 more than 100,000,000 had been made. Simple, yet effective and powerful, derivatives of this engine are still made today.

The Scorpion V8 turbo diesel engine is found in Ford F-Series pickups. It is a 6.7-liter 32-valve engine and first introduced in 2011 and is still in production.

Chevy's 409 V8 first hit the roads in 1961 and soon became a favorite of racers because of its horsepower and torque. The 6.7-liter engine could put out 425 bhp as well as 425 foot-pounds of torque. The Beach Boys even wrote a song about it titled, as you might expect, "409."

Ford picked an incredible car to put the Boss 302 Ford V8 into — the 1969 and 70 Boss 302 Mustang! It provided not only power but reliability, getting 290 hp and 290 foot-pounds of torque. The engine later evolved into the Boss 351 V8.

Found in Corvettes and other Chevy models in the mid-1960s, the L36 four-barrel 427 produced 390 brake horsepower in 1966. When coupled with three two-barrel carbs the next year, the output increased to 400 hp.

Today, the 50 to 80 horsepower produced by Chevy's straight-six engine (depending on the year and model) seem paltry, but it was a very advanced engine for its time. First released in 1929, it used overhead valves in a time when most other engines in pickups were flatheads. Versions of this engine were made until 1990 in North America and longer in other areas of the word.

First introduced by the name "Triton" in 1997 and produced by Ford through 2010, the Triton V10 is a 6.8-liter single-overhead-cam engine and an example of the Ford Modular small block engine design.

The LS9/LSA Chevy V8 engine was first seen in the 2009 ZR1 Corvette. It produces a staggering 638 horsepower, thanks to a 6.2-liter displacement and a supercharger!

The Zephyr engine was produced by Ford in the United Kingdom in the 1950s and 1960s, made in straight-four and straight-six configurations. The 1951 engine, the first produced, had a 1.5-liter displacement and produced around 47 brake horsepower. The engine powered, among other models, the Ford Consul, Zephyr and Zodiac.

This Chevrolet straight-six engine, often called the Stovebolt, was introduced by Chevrolet in 1929. It replaced the older straight-four engine and was used on a variety of Chevrolet vehicles. The engine was available in many different sizes, ranging from 3.0- to 4.8-liter units.

A big block V8, Chevrolet looks to build on the success of their SB2 NASCAR engine with the R07, first introduced in 2007. It too proved a massive success and powered Chevrolet NASCAR models to many wins.

The 351 Windsor was introduced by Ford to bridge the gap between big block and small block engines. First introduced in 1969, like many other performance engines of the time, it suffered under the mid-1970s oil crisis. It did appear in the 1995 Mustang Cobra R, however.

Chevrolet came up with the 454 big block V8 especially for its performance models. Cars such as the Camaro, Chevelle and Corvette all came with the option of the 454 engine. Everyone loved this powerplant when it was introduced in 1970. Sadly, the oil crisis of the mid-1970s saw it only produced in these cars till around 1974 before it became an option only for heavy-duty trucks.

Produced for a 31-year period between 1965 and 1996, the 300 I6 from Ford was a stalwart of their F-Series trucks. So impressive was this engine that Ford used it in heavy-duty truck models as well — and UPS delivery trucks have used this engine for years.

Dubbed the "Mystery" engine, this 427-cubic inch V8 was fast — so fast that it dominated in the 1963 NASCAR season. Sadly, it never reached any sort of potential in the 1960s as General Motors pulled out of organized racing at that time.

The SB2 (Small Block Second Generation) NASCAR engine was the first that Chevrolet developed solely for NASCAR. It was an immediate hit, taking Jeff Gordon to 13 wins in 1998, along with the championship.

The Series M Copper-Cooled vehicle used an engine that employed air cooling; there was no radiator. This was a 2.2-liter, four-cylinder powerplant that sadly, was not much of a success, especially in warm weather when it lost a lot of power.

Produced between 1940 and 1950, the Ford GAA engine was a 60-degree V8 motor made from aluminum. This 18-liter engine was used in many tank models during those years.

Introduced in 2011, the Power Stroke V8 is a 6.7-liter engine that produces 390 horsepower and more than 700 foot-pounds of torque. Powerful!

Produced for a period of 18 years from 1958 to 1976, the FE ("Ford-Edsel") engine was a V8 motor that ranged from 5.4- to 7.0-liter displacement and was used in a number of different models, including trucks.

The Chevrolet Big Block engine was the backbone of Chevy vehicles from 1955 through 2009. This model, part of Generation V (there were seven generations in all), had a top-of-the-line version called the "Ram Jet 502."

Reliable and strong, the 300 I6, part of the fourth generation of the Ford inline-six-cylinder engine series, was a popular one for the company when it was first introduced in 1965. So versatile was this engine that it could be found in a range of models as well as agricultural equipment, trucks and tractors.

First introduced in 2012, the 1.0-liter Fox Ford EcoBoost engine is a three-cylinder engine. It can produce an impressive 123 horsepower.

This engine was used in the Chevrolet Corvair in the 1960s. It is a flat-six powerplant and was available as a 2.3, 2.4 or 2.7-liter. It was a very different design from what General Motors was using at the time.

A collaboration between Chevy and England's Ilmor Engineering, the Chevrolet/Ilmor 2.65 Liter Turbo V8 won 64 out of 78 races and six consecutive Indy 500s. Incredible!

First introduced in 2012, the 1.5-liter Dragon EcoBoost engine is a three-cylinder engine developed by Ford. The top-of-the-range version, found in the Ford Fiesta ST, produces 200 horsepower.

The first generation of the Ford straight-6 engine, the 226 Flathead was a 3.7-liter engine that produced 90 horsepower. The engine was introduced for the 1941 model year.

First introduced in 2012, the Chevrolet Indy V6 is still used in the IndyCar racing series. It is a 2.2-liter 24-valve DOHC powerplant made out of aluminum. It weighs just 248 pounds.

Introduced in 1981, The Ford Essex V6 was so named as it was produced in Canada at Ford’s Essex Engine Plant in Ontario. It started as a 3.8-liter displacement engine, but a 4.2-liter eventually followed for use in F-Series pickups.

The Duratec engine was introduced by Ford in 1993 originally designed by Ford and Porsche and still is in use today. The model pictured here is a 2009 Duratec 1.3-liter Zetec-SE/Sigma type.
