With any muscle car or performance car, the heart and soul of the car is the engine. Whether that means
the rumbling V8 of a Mustang, the V12 from a Lamborghini, or even the high-revving inline 6 from an
older Skyline. The engine of the car makes it have the personality and character that the car takes on
in addition to the actual performance of the car. The engine of a car can be the deciding factor in a
purchase often, especially with cars like the Mustang which offers a variety of engines to suit
different budgets, performance brackets, and market niches. The Mustang has a rich history filled with many incredible motors powering America’s favorite sports car.
From its humble beginnings with an inline-6 that put out 120 horsepower to today’s Shelby GT500 with a
staggering 760 horsepower, the Mustang has always been about the motor in the platform to ensure the
best driving experience at any power output. There have been motors that stand out in the Mustang’s
history though, which all have been impressive even among competition from other engines in different
ways.

The Boss 429 was designed as a higher-performance version of the already impressive Boss 302 in the late
1960s and has become one of the rarest mass-produced muscle cars to ever come from Ford. The 429 was an
evolution over the Ford 385 engine and found its way into under 1,400 total cars. The 429 was a massive
7 liter V8 with a maximum horsepower output of 375 horsepower, and the sheer size of the engine required
the car to have upgraded shocks and bracing to contain and control it. While 375 horsepower may not seem
like much by today’s standards, that was only what Ford told the public it made while it was actually
over 400 horsepower. This made it one of the most powerful cars in the world at the time, with the most
powerful car being the Camaro ZL1 at over 500 horsepower at the time. Additionally, Ford built an even
higher performance version of the 429 called the Super Cobra Jet which gained an additional 15
horsepower for what at the time was $500 which is just around $3,800 today.
While the Mustang is known to be a V8 muscle car, one model and engine that deserve major recognition is
the SVO. The 2.3 liter
turbocharged 4 cylinder motor was rated to the same horsepower as the V8 at the
time. The SVO had up to 205 horsepower, competitive with today’s horsepower figures in some cars even.
Designed as a lightweight and more handing-oriented car, the SVO used its turbocharged motor to compete
with European and Japanese rivals as they came to the market in greater numbers. The SVO Mustang became
a cult classic for the motor’s performance, ease of upgrading, and simply for being different from the
normal Mustang.
For years, there were no truly powerful Mustangs as a result of the oil crisis in the 1970s but at the
beginning of the 1980s, the
big 5.0L V8 made its return to the Mustang. However, the one that truly
stood out came in 1993 in the form of the race-bred Cobra R. Fitted without options like the radio, air
conditioning, power windows or seats, and more, the Cobra R was only available to buy if you had an SCCA
or NHRA membership. While not as powerful as the older V8 motors, the 235 horsepower was more than
enough to rocket this lightweight track special into the history books as one of the most desirable
Mustangs ever.
The Cobra R returned for
its third time in 2000 with the most ridiculous build yet. Fitted with side-exit
exhaust, a massive front splitter, and rear wing, and ultralight wheels, the Cobra R was as close to a
purpose-built race car for the road that the Mustang had ever been. Ford chose to downsize from the 5.8L
engine from the 1995 Mustang Cobra R to a 5.4L engine which screamed to the tune of 385 horsepower,
making
it one of the most powerful Mustangs built at the time. The motor was simple and straightforward but was
more than effective at pushing the Cobra R to modern performance specs including a 12-second
quarter-mile time. The Cobra R has not returned since the 2000 model year to the Mustang market.
While the Mustang has always had performance in its DNA, the 03-04 Cobra Mustang brought it out in a very
different way. These cars came with independent rear suspension, a powerful Tremec, and most importantly
a supercharged 4 valve motor. This meant that the car could rev higher and make more power which came to
just shy of 400 horsepower. The car was nicknamed “Terminator” for a
reason - these cars absolutely
walked over their competition to the point of allegedly killing off the Firebird and Camaro; terminating
them. These cars and specifically their engines have gotten much more expensive as the performance
community has
continued to modify them since the block is very durable and capable of holding tons of power.
The 5.4L supercharged V8 found in the 2007 Shelby GT500 was a welcome surprise for the Mustang community
since the normal GT was only holding at 300 horsepower as its rivals kept improving further. The GT500
put out 500 horsepower which brought it up into a new class of performance car. This was the first major
horsepower jump for the Mustang in decades outside of the 2000 Cobra R over the normal Cobra. The 5.4
proved itself to be tough with its iron construction which was eventually replaced when the engine was
upgraded later on.
The Coyote V8 and Roadrunner siblings were incredibly impressive from a technological standpoint. The
dual overhead camshaft design and twin independent variable camshaft timing both helped the Coyote motor win
awards when it was new for technological advancement. These allowed the car to rev higher, put
out
more power, and get better fuel economy at the same time. While companies like Chevy and Dodge continued
running larger displacement engines in order to get power, this new technology from Ford allowed a 5.0
liter to put out the same power as the 5.7L Hemi and the 6.2L LS3 motors. The Roadrunner, which was
designed as a more racing-oriented version of the Coyote, was fitted in the Boss 302 with forged
connector rods, short runner intake manifold, ported heads, larger camshafts, and stiffer valve springs.
The end result was essentially a road-legal road racing engine for mass production.
The largest motor to grace the Mustang in recent history, the 5.8 liter Trinity V8 was fitted in the 2013
and 2014 Shelby GT500 and was a powerhouse of an engine even compared to today. With a maximum output of
662 horsepower, the supercharged 5.8 liter V8 was enough to propel the car to 60 miles per hour in about
4 seconds, faster than any of the rivaling vehicles at the time. With an aluminum block, the 5.8 was
fairly lightweight compared to similarly-sized engines and punched well above its weight class. Like the
Terminator, Cobra R, and 5.4L, the 5.8L motor was only available with a manual 6-speed gearbox.
The Voodoo motor is a unique one in the Mustang’s history as it is the only flat-plane crank motor to be
in the car. The Voodoo was designed in the same vein as the Roadrunner - as a roadgoing racing engine
for the masses to be able to enjoy. The GT350 and GT350R which house this motor were designed to be
track cars and rev up to 8,250 rpm, further than any Mustang outside of actual racing vehicles. These
cars also have a very distinct exhaust note because of the flat-plane crank and displacement, making
them sound more similar to exotic cars than the Mustang.
Built off of the bones of the Voodoo, the Predator motor is the next step from the 5.8L supercharged
Trinity motor in the GT500. There are two main differences between the Voodoo and Predator motors; one
of which is the supercharger found on the Predator, while the other is the lack of the flat-plane crank
which makes the Predator sound more like a Mustang than the GT350 does. With 760 horsepower and 625
lb-ft of torque, the GT500 is the most powerful and fastest Mustang on the road from the factory. The
S550 GT500 also receives a Mustang first - a dual-clutch gearbox that provides lightning-fast shifting.
The Cobra Jet 1400 is an odd-one-out for the Mustang and especially for the name “Cobra Jet”. The
original Cobra Jet was an incredibly powerful V8 Mustang and afterward became the order-only factory
dragster that would pull wheelies and run the quarter-mile in the 8-second range at over 150 miles per
hour. The new Cobra Jet 1400 however is a 1,400 horsepower fully electric dragster that will run the
same time with the added weight of the four electric motors. While the idea of an electric Mustang is
one that many of us can’t stomach, you can’t deny the performance figures with a vehicle like this.The Best Mustang Engines Ever
