1969-2007 Ford Boss Mustang History: Shinoda, Engine, and Performance

By -

The 1964 Ford Mustang was introduced as an instant success, though few trim lines or options were offered. By 1969, however, Ford recognized the desire for faster and more powerful Mustangs, shown by the vast interest in the factory backed and modified Shelby Mustangs. In accordance with their theme of “Win on Sunday, sell on Monday”, they released a collection of new Mustang trim lines; a move that conceived the Boss Mustang, thought up by the head of Ford’s Special Design Center, Larry Shinoda.Boss302engine.jpg


1969
When introduced, the Boss Mustang was offered in two
variants: the Boss 302 and the Boss 429. The Boss 302 was basically a
high performance fastback Mustang, with some aesthetic upgrades to
accompany the beefed up 302 cubic inch engine. The standard 302 (F
Code) made 220 horsepower, but the Boss 302 (G Code) engine offered an
extra 70 horsepower. Along with the upgraded engine the Boss 302 trim
line included a partially blacked out hood with a raised center
section, a front air dam, a rear spoiler, the side scoops were deleted,
and along the sides of the car were prominent decals which held the
Boss 302 logos. Production of the 1969 Boss 302 was limited to 1,628
units. However, the Boss 302 was only the tip of the iceberg for the
Boss lineup.

The bigger news for the 1969 Ford Mustang was the
Boss 429. This trim line appeared to be more like a standard Mustang;
aesthetically it packed a whole lot more punch. It did not carry the
wing, front air dam, or dramatic side decals like the Boss 302, but it
did feature a large functional hood scoop, and the only extra emblems
on the Boss 429 were small decals on the front fenders. While the Boss
429 did not have the standard non-functional scoops in front of the
rear wheels, it did have the opening mounted high on the rear quarter
panels. The most important upgrade was where the Boss 429 derived its
name, and that was the NASCAR inspired 429 cubic inch hemispherical
head engine. This ‘street version’ of the NASCAR engine offered the
driver 376 horsepower, making it the most powerful Mustang offered to
date next to the 11 GT350S models made in 1966. Each of the 867 Boss
429 Mustangs were hand built by Kar Kraft of Brighton Michigan, and
production ran from January to July of 1969. The lucky owners of those
limited units could chose from Raven Black, Royal Maroon, Black Jade,
Candy Apple Red, or Wimbledon White, and all of the Boss 429s came with
black interiors.

1970
1970 brought about some physical
changes, such as the new headlight covers, and the Boss 302 and Boss
429 were still offered. The Boss 302 got itself some new stripes, that
came along the side of the car and up across the hood, and the hood
stripe was now narrower. The Boss 302 now had the option of the Shaker
hood, originally only offered on the Mach1. Along with these new
modifications came much bigger production numbers, and with over 7,000
units made in 1970, the Boss 302 was now much easier to acquire. The
Boss 429 now offered 1 less horsepower from 1969, but there was little
real difference. The suspension of the Boss 429 was changed from
regular Mustangs in order to accommodate the added size and weight.
Like the 1969 Boss 429, there were less physical differences from the
Boss 302, with the exception of the large hood scoop and fender badges
similar to the 1969 badges. The Boss 429 also had the badges on the
c-pillar, similar to the ones found on the Mach1. Only 499 units were
produced in 1970, and they were offered in Grabber Blue, Grabber Green,
Grabber Orange, Calypso Coral, and Pastel Blue, and either white or
black interiors could be chosen. Sadly, this would be the last year for
the mighty Boss 429, and the lower level Boss 302. There were 2 special
Boss 429 Mustangs built in 1970, and these 1200 horsepower monsters
were named the Boss 429 Lawmen Mustangs. Originally built as touring
show cars for United States Armed Forces troops, only one of the Lawmen
Mustangs exists today, and it is owned by ex-national football league
player and ex-WWF wrestler Bill Goldberg, who is a collector of vintage
high performance cars.

1971
In 1971, the Boss 302 and Boss
429 were no longer offered, but the Boss name was still present on Boss
351. The 351 had been present in 1970, but it had only made 250
horsepower, where the new Boss 351 made 330 horsepower. The Boss 351
was now mostly up upgrade package and all of the Mustang’s colors could
be chosen. Many of the appearance upgrades of the Boss 351 were the
same as the Mach1 of 1971, from the ram air hood to the stripe that ran
the length of the car. The Mach1 now had the 429 cubic inch engine
formerly found in the Boss lineup, which secured the Mach1 as the
premium performance Mustang, and marking the beginning of the end for
the Boss lineup. When the 1972 models were rolled out for the public,
there was no longer a Boss model, and the most powerful engine offered
was a 275 horsepower 351. There were no big blocks offered (and there
never again would be) due to new vehicle emissions laws, and the drop
in horsepower on the returning engines, such as the 351 high output
dropping from 330 to 275, was contributed to by the new performance
testing requirements set forth by the US government. Engines were now
required to be tested under load, with the accessories, so that there
was a more reasonable horsepower rating for the consumer. The Boss
model was only one of many fabled performance names which fell along
the wayside due to new restrictions, but the Boss name would not be
gone forever.

Boss in the Aftermarket and the Shinoda Legacy
There
would never be another factory or dealership-offered Boss Mustang, but
family members of Larry Shinoda have created Team Shinoda, and this new
company is working to continue the legend of the Boss name. The new
Boss Mustang is similar to that of a Saleen or Roush Mustang, as it is
offered only as a variety aftermarket upgrade packages, starting with
the 1994-1998 models (SN95), these packages include things such as
basic appearance modifications as well as performance upgrades, and
once the various packages are installed, the car is then eligible to be
registered as an official Boss Mustang. Once a Mustang owner has
purchased and properly installed all of the upgrades for the given
package, including a choice of wheels from an ‘approved wheel list’,
the car must then be photographed and those photos must be submitted to
Shinoda to ensure proper application for the appearance packages, and
for the performance minded packages the cars must be inspected in
person, and at that point, the car is made official.

SN95 Boss Mustang Packages
The
1994-1998 Boss Mustang is offered in there forms; the Boss Shinoda Gen
I, Boss Shinoda Gen II, and the Cobra Shinoda. The first package, the
Boss Shinoda Gen I, is an appearance package based on the items added
to the original Boss Mustang, and requires the following items for
registration:
•    Boss Shinoda Graphics
•    Boss Shinoda Chin Spoiler
•    Shinoda by Budnick Wheels
•    Export Wheel Flares
•    Boss Shinoda Super Spoiler
•    Must be inspected via photographs for registration

This
package is the best for someone who wants to display the proud Boss
name, but is less concerned with performance upgrades. However, a
driver who wants more than just some appearance modifications can opt
for the Boss Shinoda Gen II package, which includes the following items:
•    Boss Shinoda Graphics
•    Boss Shinoda Chin Spoiler
•    Approved Shinoda Wheels
•    Export Wheel Flares
•    Boss Shinoda Super Spoiler
•    Hotchkiss Caster Camber Plates
•    Shinoda Spring Kit
•    Must be inspected in person for registration

The
Gen I and Gen II items apply to the Mustang GTs made from 1994-1998,
but for Cobra owners of those same years, there is an option for them,
although it does not carry the Boss name. The Cobra Shinoda package is
similar to the Gen II package, and includes the following items:
•    Cobra Shinoda Graphics
•    Shinoda 5 Spoke Wheels 18 x 9
•    Cobra Shinoda Fender Flares
•    Cobra Shinoda Super Spoiler
•    Hotchkiss Caster Camber Plates
•    Eibach Pro Kit Lowering Springs
•    Must be inspected in person for registration

New Edge Boss Mustang Packages
Much
like the SN95 Boss upgrades, Team Shinoda offered upgrades for the
1999-2004 Mustangs (New Edge), which corresponded to the packages for
the previous generation but there were more options for more
performance minded Boss enthusiasts. The first package, the Boss
Shinoda Legacy, is a simple appearance upgrade, once against based on
the original Boss Mustang. This package includes the following items:
•    Boss Shinoda Graphics
•    Boss Shinoda Chin Spoiler
•    Shinoda 5 Spoke Wheels 17 x 8
•    Boss Shinoda Rear Super Spoiler
•    Must be inspected via photographs for registration

The
next package is another appearance package, but it takes it roots from
the 1971 Boss Mustang, thanks to the addition of the Shaker hood. The
complete list of items for the 1999-2004 Boss Shinoda Legacy GT package
is as follows:
•    Boss Shinoda Legacy GT Graphics
•    Boss Shinoda Chin Spoiler
•    Boss Shinoda Rear Super Spoiler
•    Mustang Bullitt Wheels 17 x 8
•    Hurst Retro Kit
•    Rear Black Out Panel
•    Side Scoop Delete Panels
•    Shaker Hood Kit
•    Rear Window Louvers
•    Must be inspected via photographs for registration

Similar
to the 1994-1998 Gen II packages, the 1999-2002 Boss Shinoda Level 1
offers suspension upgrades along with the familiar Boss appearance
upgrades. The complete list of required items for the 99-02 Boss
Shinoda Level 1 is comprised of:

•    Shinoda 5 Spoke Wheels 17 x 8
•    Boss Shinoda Chin Spoiler
•    Boss Shinoda Rear Super Spoiler
•    Hotchkiss Caster Camber Plates
•    Eibach Pro Kit Lowering Springs
•    Must be inspected in person for registration

The
first of the in depth performance upgrade packages was offered on 2003
and 2004 Mustang GTs, and is accompanied by the appearance and
suspension upgrades similar to the 99-02 Boss Shinoda Level 1. The
03-04 Boss Shinoda Level 1 packages includes:

•    Boss Shinoda Chin Spoiler
•    Boss Shinoda Rear Super Spoiler
•    Hotchkiss Caster Camber Plates

•    Must be inspected in person for registration

While
the 1999 and 2001 Cobras received only basic appearance and suspension
improvements, the 2003-2004 Cobras, which were so powerful and popular
that they earned themselves the nickname “Terminators”, had the option
of three different packages. These packages range from a basic

The
performance upgrades which are offered for the 2003-2004 Cobra make
those Shinoda Mustangs the most powerful up to 2004, with the exception
of the Boss 429 Lawman models, but with the introduction of the wide
variety of packages offered for the popular new “retro-look” 2005 and
newer Mustang, Shinoda was back to the drawing board, and they did not
disappoint.

S197 Boss Mustang Packages
When Ford
redesigned the Mustang for the 2005 mode year, it was no secret that
they were going for a modern look to the original design, and they hit
that right on the head. Enthusiasts, both old and new were instantly in
love with this new Mustang, so it would make perfect sense that the
Boss Mustang lineup would return, and as with the original, the new
Boss is better than ever. The 2005-2006 Mustang has the option of 5
different trim lines, starting with the Boss Shinoda Legacy, then the
Boss Shinoda Levels 1, 2, and 3, and finally the Boss Shinoda Stroker.

2005 Boss Shinoda Legacy includes the following items, and is available
in a variety of colors, allowing the owner some customization for his

next group of packages are levels of the Boss Shinoda Package, and like
the packages offered for the 2003-2004 Cobras, these range from
appearance and minor performance upgrades to all out performance. The
level 1 kit adds some power along with suspension upgrades, allowing
the car to perform better and carry the Boss look. The level 2 kit adds

turbo kit.

The
Boss Mustang ripped onto the scene in 1969, setting the pace for high
performance Mustangs on the road course or the drag strip. Boss Mustang
is likely to keep making a name for itself for generations to come with
high performance upgrades and sporty interior and exterior upgrades.
While Larry Shinoda is no longer with us, there is a pretty good chance
that he would have been very proud of these new ultra high performance
Boss Mustangs, which carry his name as well as the Boss legacy that he
helped to introduce in 1969.

– Patrick Rall

Had a Shinoda Boss? What are your memories of them? How did it compare to the other trims and engine configurations? Have factory backed engine upgrades lost their usefulness? Always better to go with a base GT and upgrade through the aftermarket?
