1964-2009 Ford Mustang Classic to Modern Engine History: Horsepower, Supercharged and Turbocharged

 
 
P

The 1964-2009 Ford Mustang has spent 42 years as one of the leading names in the American performance car market, and one of the best selling cars in US history.  While the sleek, sporty lines get the attention, the Ford Mustang never fails pack a strong-running engine. Ford also always offers at least one small, efficient, economical Mustang engine for those more concerned with the look of the Mustang than they are with brute performance. Here a brief overview of the engines offered over the years since the Mustang was introduced.

1964
Ford had no idea that the 1964 Mustang would be such a hit, so it was offered with only three engines:

-170 cubic inch inline 6, naturally aspirated, 1 bbl carbureted, 101 horsepower
-260 cubic inch V8, naturally aspirated, 2 bbl carbureted, 164 horsepower
-289 cubic inch V8, naturally aspirated, 4 bbl carbureted, 210 horsepower


1965
It did not take long for the Mustang to become popular, for which the Ford Motor Company saw a need to make higher performance models: the 1965 Ford Mustang GT was introduced and racing legend Carroll Shelby started making the famed Shelby Mustangs, beginning with the GT350.

Boss 351:
-351 cubic inch V8, naturally aspirated, 4 bbl carbureted, 330 horsepower

1972
The 1972 Ford Mustang had to endure US Government implemented new engine emissions regulations, which required engines be tested for horsepower ratings under load of all accessories such as power steering, the alternator, etc. This caused a drop in stated horsepower, though the actual horsepower did not change much; it was just stated differently. Nonetheless, the new restrictions negatively impacted the sales of all performance cars, not just the Mustang.

Base:
-250 cubic inch inline 6, naturally aspirated, 1 bbl carbureted, 98 horsepower
-302 cubic inch V8, naturally aspirated, 2 bbl carbureted, 140 horsepower

Mach1:
-302 cubic inch V8, naturally aspirated, 2 bbl carbureted, 140 horsepower
-351 cubic inch V8, naturally aspirated, 2 bbl carbureted, 177 horsepower
-351 cubic inch V8, naturally aspirated, 4 bbl carbureted, 266 horsepower
-351 cubic inch V8, naturally aspirated, 4 bbl carbureted, 275 horsepower


1973
The 1973 Ford Mustang marked the end of the first generation. When the 1974 Mustang was released, it appeared as though the Ford Motor Company was no longer attempting to manufacture a performance car. The performance-minded 1973 Mach1 Mustang experienced another drop in power.

Base:
-250 cubic inch inline 6, naturally aspirated, 1 bbl carbureted, 99 horsepower
-302 cubic inch V8, naturally aspirated, 2 bbl carbureted, 141 horsepower

Mach1:
-302 cubic inch V8, naturally aspirated, 2 bbl carbureted, 141 horsepower
-351 cubic inch V8, naturally aspirated, 2 bbl carbureted, 177 horsepower
-351 cubic inch V8, naturally aspirated, 4 bbl carbureted, 266 horsepower


1974
The 1974 Ford Mustangs hit the showroom floor as if it was a whole new car, and so it was named the Mustang II. The Mustang II did not look like its predecessor nor did it run like it either, mostly due to a relatively weak engine lineup. The 1974 Mustang lineup lacked a performance model once again, although there would be the Ghia, which was just a luxury upgrade. The Mach1 returned, but without a performance engine.

Base, Mach1, and Ghia:
-140 cubic inch inline 4, naturally aspirated, 2 bbl carbureted, 88 horsepower
-171 cubic inch V6, naturally aspirated, 2 bbl carbureted, 105 horsepower

1975
The 1975 Ford Mustang went without a performance model as well, but also introduced "Five-O" Mustang. With only a base Mustang or a Ghia, the 5 liter V8 was a welcome addition to the Mach1.

Base, Mach1, and Ghia:
-140 cubic inch inline 4, naturally aspirated, 2 bbl carbureted, 88 horsepower
-171 cubic inch V6, naturally aspirated, 2 bbl carbureted, 105 horsepower
-302 cubic inch V8, naturally aspirated , 2 bbl carbureted, 140 horsepower

1976
The 1976 Ford Mustang carried an implication that the Shelby had returned with the Cobra II, adopting the roman sequence of the new Mustang II. Unfortunately, there was still no high performance engine offered; the Cobra II was basically an appearance package and the engine offerings did not change.

Base, Mach1, Ghia, and Cobra II:
-140 cubic inch inline 4, naturally aspirated, 2 bbl carbureted, 88 horsepower
-171 cubic inch V6, naturally aspirated, 2 bbl carbureted, 105 horsepower
-302 cubic inch V8, naturally aspirated , 2 bbl carbureted, 140 horsepower

1977
The 1977 Ford Mustang saw subtle appearance changes in an attempt to make the Mustang II look a bit sportier but, again, no engine changes.

-140 cubic inch inline 4, naturally aspirated, 2 bbl carbureted, 92 horsepower
-171 cubic inch V6, naturally aspirated, 2 bbl carbureted, 103 horsepower
-302 cubic inch V8, naturally aspirated , 2 bbl carbureted, 140 horsepower

1978
The 1978 Ford Mustang was the final Mustang II, and the last year the public had to tolerate low performance engines. The following year introduced the most popular Mustang body, possibly ever.
-140 cubic inch inline 4, naturally aspirated, 2 bbl carbureted, 92 horsepower
-171 cubic inch V6, naturally aspirated, 2 bbl carbureted, 103 horsepower
-302 cubic inch V8, naturally aspirated , 2 bbl carbureted, 140 horsepower

1979
The1979 Ford Mustang introduced the Fox Body chassis, which, with a few changes over the years, would remain the Mustang chassis all the way to 1993. It was during this time that the Mustang came to be known as the "five-o;" though the Mustang II had the engine, this chassis made the term famous. Furthermore, Ford offered an option in power with their 2.3L turbocharged 4 cylinder. This was also the year that Ford began stating their engines sizes by liters rather than cubic inches. The engines offered were available in all forms of the car, as there was no GT, or similar performance model.  There was the Cobra, but it was basically a trim package.
-2.3 liter inline 4, naturally aspirated, 2 bbl carbureted, 88 horsepower
-2.3 liter inline 4, turbocharged, 2 bbl carbureted, 132 horsepower
-2.8 liter V6, naturally aspirated, 2 bbl carbureted, 109 horsepower
-3.3 liter inch V6, naturally aspirated, 1 bbl carbureted, 85 horsepower
-5.0 liter V8, naturally aspirated, 2 bbl carbureted, 140 horsepower

1980
There were still no performance models offered in 1980, so once again all engines were offered on all Mustangs sold.  The 5.0 liter engine was not offered in 1980, but would return in a few years.  In its place for the time being was a 4.2L engine that was less powerful.  In an effort to make the automatic transmission Mustangs as quick as the manual transmission models, the 2.3L and 3.3L Mustangs with auto transmissions got a slight bump in bhp.
-2.3 liter inline 4, naturally aspirated, 2 bbl carbureted, 88 horsepower (manual trans only)
-2.3 liter inline 4, naturally aspirated, 2 bbl carbureted, 90 horsepower (automatic trans only)
-2.3 liter inline 4, turbocharged, 2 bbl carbureted, 132 horsepower
-3.3 liter V6, naturally aspirated, 2 bbl carbureted, 91 horsepower (manual trans only)
-3.3 liter inch V6, naturally aspirated, 1 bbl carbureted, 94 horsepower (automatic trans only)
-4.2  liter V8, naturally aspirated, 2 bbl carbureted, 119 horsepower

1981
Again, no performance models and no 5.0L, and 1981 also saw the drop of the turbocharged 2.3L.  Not a particularly exciting year for the Mustang engine lineup.
-2.3 liter inline 4, naturally aspirated, 2 bbl carbureted, 88 horsepower
-3.3 liter inch V6, naturally aspirated, 1 bbl carbureted, 94 horsepower
-4.2  liter V8, naturally aspirated, 2 bbl carbureted, 120 horsepower


1982
Finally, the 5.0L would return, and this time it would stick around until 1995, and this period was what cemented the 5.0L in motoring history.  However, the addition of the Mustang GL, GT, and GLX hinted at possible upcoming, performance Mustangs as were seen in the 60s and 70s.

Base:
-2.3 liter inline 4, naturally aspirated, 2 bbl carbureted, 88 horsepower
-3.3 liter inch V6, naturally aspirated, 1 bbl carbureted, 94 horsepower

Mustang GT/GLX:
-4.2  liter V8, naturally aspirated, 2 bbl carbureted, 120 horsepower
-5.0 liter V8, naturally aspirated, 2 bbl carbureted, 157 horsepower


1983
The biggest news for the Mustang in 1983 was the long await return of the convertible.  However, the engine lineup was also refreshed for 1983, and that refresh including the removal of the 4.2L and 3.3L, the addition of a 3.8L V6 and a new turbocharged, fuel injected 2.3L, and the 5.0L got a sizeable jump in power.

Base:
-2.3 liter inline 4, naturally aspirated, 1 bbl carbureted, 88 horsepower
-3.8 liter inch V6, naturally aspirated, 2 bbl carbureted, 112 horsepower

Mustang GT:
-2.3 liter inline 4, turbocharged, fuel injected, 145 horsepower
-5.0 liter V8, naturally aspirated, 4 bbl carbureted, 176 horsepower

1984
1984 marked the (illegal) return of the GT350, as well as the introduction of the SVO Mustang.  There were additional 5.0L engines offered, now featuring fuel injection.  This year marked the introduction of the Saleen Mustang, although it would be a while before Saleen began making engine performance alterations.

Base:
-2.3 liter inline 4, naturally aspirated, 1 bbl carbureted, 88 horsepower
-3.8 liter inch V6, naturally aspirated, fuel injected, 120 horsepower

Mustang GT:
-2.3 liter inline 4, turbocharged, fuel injected, 145 horsepower
-5.0 liter V8, naturally aspirated, fuel injected, 165 horsepower
-5.0 liter V8, naturally aspirated, 4 bbl carbureted, 175 horsepower

GT350:
-2.3 liter inline 4, turbocharged, fuel injected, 145 horsepower
-5.0 liter V8, naturally aspirated, 4 bbl carbureted, 175 horsepower

SVO:
-2.3 liter inline 4, turbocharged, fuel injected, 175 horsepower


1985
The GT350 was gone in 1985, but the SVO returned.  There would be power increases for the SVO 2.3L and the 5.0L HO motor, although the Turbo GT wasn't offered.
Base:
-2.3 liter inline 4, naturally aspirated, 1 bbl carbureted, 88 horsepower
-3.8 liter inch V6, naturally aspirated, fuel injected, 120 horsepower

Mustang GT:
-5.0 liter V8, naturally aspirated, fuel injected, 165 horsepower
-5.0 liter V8, naturally aspirated, 4 bbl carbureted, 210 horsepower

SVO:
-2.3 liter inline 4, turbocharged, fuel injected, 205 horsepower


1986
Nothing new was added in the engine lineup for 1986, but the 5.0L carbureted engine was removed.  This would be the final year for the SVO.

Base:
-2.3 liter inline 4, naturally aspirated, 1 bbl carbureted, 88 horsepower
-3.8 liter inch V6, naturally aspirated, fuel injected, 120 horsepower

Mustang GT:
-5.0 liter V8, naturally aspirated, fuel injected, 200 horsepower

SVO:
-2.3 liter inline 4, turbocharged, fuel injected, 205 horsepower


1987
While still based on the fox body chassis, the 1987 Mustang got a fairly elaborate refresh, with a new sportier look, which yielded better aerodynamics.  There would be only two engines offered, as the only options were the base model, the GT, and the Saleen, although the Saleen still used the basic GT engine.

Base:
-2.3 liter inline 4, naturally aspirated, 1 bbl carbureted, 88 horsepower

Mustang GT:
-5.0 liter V8, naturally aspirated, fuel injected, 225 horsepower


1988
There were very few changes for the Mustang in 1988, and none were made to the engine offerings.

Base:
-2.3 liter inline 4, naturally aspirated, 1 bbl carbureted, 88 horsepower

Mustang GT:
-5.0 liter V8, naturally aspirated, fuel injected, 225 horsepower


1989
There were no changes to the Mustang or the engine lineup, but the Saleen models got their first increase in horsepower.

Base:
-2.3 liter inline 4, naturally aspirated, 1 bbl carbureted, 88 horsepower

Mustang GT:
-5.0 liter V8, naturally aspirated, fuel injected, 225 horsepower

Saleen SSC:
-5.0 liter V8, naturally aspirated, fuel injected, 292 horsepower


1990
Once again, no big changes for the engine lineup of the GT or base model, but the Saleen models got a few changes.  The base model 4 cylinders finally got fuel injection, but no gain in power.

Base:
-2.3 liter inline 4, naturally aspirated, fuel injected, 88 horsepower

Mustang GT:
-5.0 liter V8, naturally aspirated, fuel injected, 225 horsepower

Saleen:
-5.0 liter V8, naturally aspirated, fuel injected, 292 horsepower

Saleen SC:
-5.0 liter V8, naturally aspirated, fuel injected, 304 horsepower


1991
The only change for 1991 was an upgrade in power for the base model.

Base:
-2.3 liter inline 4, naturally aspirated, fuel injected, 105 horsepower

Mustang GT:
-5.0 liter V8, naturally aspirated, fuel injected, 225 horsepower

Saleen:
-5.0 liter V8, naturally aspirated, fuel injected, 292 horsepower

Saleen SC:
-5.0 liter V8, naturally aspirated, fuel injected, 304 horsepower


1992
By 1992, perhaps people had begun to grow bored with the Mustang, as sales had been slumping for a few years.  The Saleen group did make a few Mustangs in 1992, but none of the SC models were made.

Base:
-2.3 liter inline 4, naturally aspirated, fuel injected, 105 horsepower

Mustang GT:
-5.0 liter V8, naturally aspirated, fuel injected, 225 horsepower

Saleen:
-5.0 liter V8, naturally aspirated, fuel injected, 292 horsepower

1993
This would be the final year for the popular fox body Mustang, and there were several special edition Mustangs made for the final model year of the fox body.  One of those special edition Mustangs came from Ford's recently developed "Special Vehicle Team", who produced the 1993 Cobra R.

Base:
-2.3 liter inline 4, naturally aspirated, fuel injected, 105 horsepower

Mustang GT:
-5.0 liter V8, naturally aspirated, fuel injected, 205 horsepower

SVT Cobra R
-5.0 liter V8, naturally aspirated, fuel injected, 235 horsepower

Saleen:
-5.0 liter V8, naturally aspirated, fuel injected, 292 horsepower

Saleen SC:
-5.0 liter V8, naturally aspirated, fuel injected, 304 horsepower

Saleen SA-10:
-5.0 liter V8, supercharged, fuel injected, 320 horsepower

Saleen RRR:
-5.0 liter V8, supercharged, fuel injected, 576 horsepower


1994
This was the first year of the new Mustang chassis, named the SN95.  There would be no more 4 cylinder Mustangs offered, and in its place a V6 as the base model engine.  There were two different versions of the 5.0L for 1994; one for the GT, and one for the Cobra.  The Saleen models got a big jump thanks to an entirely different engine.  Also for 1994, Roush Performance and Shinoda began offering modifications for Mustangs, but they offered no different engines, and the modifications could be applied to any model Mustang.

Base:
-3.8 liter V6, naturally aspirated, fuel injected, 145 horsepower

Mustang GT:
-5.0 liter V8, naturally aspirated, fuel injected, 215 horsepower

Cobra:
-5.0 liter V8, naturally aspirated, fuel injected, 240 horsepower

Saleen V6 Sport:
-3.8 liter V6, naturally aspirated, fuel injected, 145 horsepower

Saleen S351:
-5.8 liter V8, supercharged, fuel injected, 371 horsepower

Saleen SR:
-5.8 liter V8, supercharged, fuel injected, 480 horsepower


1995
This year, nothing changed for the base model of GT Mustangs.  Shinoda and Roush continued offering handling and appearance upgrades, and the Saleen lineup saw little change other than the drop of the V6 Sport.  The big news was the release of the 1995 Cobra R from SVT.

Base:
-3.8 liter V6, naturally aspirated, fuel injected, 145 horsepower

Mustang GT:
-5.0 liter V8, naturally aspirated, fuel injected, 215 horsepower

Cobra:
-5.0 liter V8, naturally aspirated, fuel injected, 240 horsepower

Cobra R:
-5.8 liter V8, naturally aspirated, fuel injected, 300 horsepower

Saleen S351:
-5.8 liter V8, supercharged, fuel injected, 371 horsepower

Saleen SR:
-5.8 liter V8, supercharged, fuel injected, 480 horsepower


1996
This was the year that the performance car market saw another disappearance of the 5.0L V8, and this time, it would be for good.  Replacing it was the new 4.6L modular motor, and this marked the first time that an overhead cam engine would grace a production Mustang.  There was no more Cobra R, as it was a one year model.  The Roush, and Shinoda models remained the same, but Saleen would mix things up a bit with a big increase to the S351 power, the drop of the SR, and the addition of the S281.  The V6 base model also got an additional 5 horsepower.

Base:
-3.8 liter V6, naturally aspirated, fuel injected, 150 horsepower

Mustang GT:
-4.6 liter V8, naturally aspirated, fuel injected, 215 horsepower

Cobra:
-4.6 liter V8, naturally aspirated, fuel injected, 305 horsepower

Saleen S281:
-4.6 liter V8, naturally aspirated, fuel injected, 215 horsepower

Saleen S351:
-5.8 liter V8, supercharged, fuel injected, 495 horsepower

1997
In 1997, almost nothing changed in the world of the Mustang.  The Saleen models were the same, as were the Roush and Shinoda models, and the base, GT, and Cobra received no engine changes.

Base:
-3.8 liter V6, naturally aspirated, fuel injected, 150 horsepower

Mustang GT:
-4.6 liter V8, naturally aspirated, fuel injected, 215 horsepower

Cobra:
-4.6 liter V8, naturally aspirated, fuel injected, 305 horsepower

Saleen S281:
-4.6 liter V8, naturally aspirated, fuel injected, 215 horsepower

Saleen S351:
-5.8 liter V8, supercharged, fuel injected, 495 horsepower


1998
The Mustang GT got 10 extra horsepower for 98, but the Cobra and V6 would remain the same in this, the last year of the SN95.  The Roush and Shinoda models were still basically appearance and handling packages, along with some offered power adders, but they used the basic Mustang GT engines.  To commemorate another anniversary, Saleen offered the SA-15.

Base:
-3.8 liter V6, naturally aspirated, fuel injected, 150 horsepower

Mustang GT:
-4.6 liter V8, naturally aspirated, fuel injected, 225 horsepower

Cobra:

1999
A new year for the Mustang brought about a new body style, with the launch of the New Edge Mustang.  The 4.6 and 3.8L engines were still present, with new power ratings.  There would be Roush Mustangs sold in 1999 and 2000, but no engine alterations, and the same stood for Shinoda.  Saleen models would remain the same as 1998.  The Cobra received a reported gain of 15 horsepower, but dyno testing proved that the 1999 Cobra failed to make the listed 320hp.  The cars were all recalled, modified, and returned with the proper 320 horsepower.

2000
After the embarrassing horsepower error of 1999, there was no Cobra offered for 2000, but there was the third edition of the Cobra R, and this one proved to be the best yet.  Saleen dropped the S351 in 2000, making the S281 the only option.  Roush and Shinoda were still offering modifications to GTs.

2001
Having ironed out the low horsepower numbers of the 99 Cobra, Ford re-released the Cobra in 2001, and they measured up to expectations this time.  Saleen saw no change, but Roush finally debuted their new supercharged 4.6L in the stage 3 and special edition models.

There were no Cobras built for the US in 2002, although there were some made for export.  Things remained the same for Shinoda, while Roush and Saleen all added new horsepower numbers.

2003
This year marked the release of a new Cobra, which would earn itself a nasty reputation and nickname...the Terminator.  Packed with a factory supercharger, the new Cobra became an instant legend.  Although overshadowed by the Cobra, the return of the Mach1 offered similar power to the older Cobras, and more power than the GT.

2005
In 2005 Ford released their new body style once again with the S197 body style.  An obvious retro version of the original, the 2005 Mustang was a tremendous success.  More horsepower was offered across the boards, both from Ford and from the aftermarket tuners.

2007
While the 2007 Ford Mustang base model, GT, Saleen, and Roush offerings received little change, a Mustang icon returned. For the first time in over 35 years, the Shelby name graced the body of a production Ford Mustang, thanks to the 2007 Ford Mustang Shelby Cobra GT500. Packed with the supercharged 5.4L engine previously found in the Ford GT Supercar, the return of the Shelby and GT500 names to the Mustang have proven to be great ones. Note: Shinoda Boss Mustangs registered with either Shinoda's Twin Turbocharger or Supercharger kit.
