Shelby Mustang Up To 1970

They were assembled between 1965 to 1967 and then 1969 to 1971 in Los Angeles, California and in 1968 in Ionia, Michigan.

Shelby American

It was a Pony car and a Muscle car on a Ford D2C platform
The Shelby Mustang is a high performance variant of the Ford Mustang which was built by Shelby from 1965 to 1968, and from 1969 to 1970 by Ford.

1st generation (1965–1972)

1965–1966 Shelby G.T.350
1965 Shelby Mustang G.T.350
1966 Shelby G.T.350

Shelby G.T.350

The Production was between 1965 and 1966 and was assembled in Los Angeles, California.
Its Body style was a:
1. 2-door fastback
2. 2-door convertible
3. 2-door hardtop
Its Engine was a 289 cu in (4.7 L) Windsor V8 2-barrel and it had a 3-speed automatic and 4-speed manual
Its Wheelbase was 108.0 in (2,743 mm) and its Length was 181.6 in (4,613 mm).

1965 G.T.350R

The 1965–1966 cars were the smallest and lightest of the GT 350 models.
These cars are often called “Cobras”.
Both models use the Cobra emblem, similar paint scheme, and the optional “Cobra” valve covers on many GT350s that were part of a marketing tie-in by Shelby, as well as one of his iconic symbols.

All 1965–66 cars featured the K-Code 271 hp (202 kW; 275 PS) 289 cu in (4.7 L), modified to produce 306 hp (228 kW; 310 PS).
Beginning as a stock Mustang with a 4-speed manual and 9″ live rear axle, the cars were shipped to Shelby American, where they received:
1. The high-riser manifolds
2. Tri-Y headers
3. Larger Ford Galaxie rear drum brakes with metallic-linings
4. Kelsey-Hayes front disc brakes.The 1965 G.T. 350 was not built for comfort or ease of driving.
There were 34 “G.T. 350R” race-spec cars built specifically for competition use under SCCA rules, and the model was the B-Production champion for three straight years.

The 1966 G.T. 350 had featured more comfort of casual drivers that included:
• Rear seats
• Optional colors
• An optional automatic transmission.
This trend for additional features continued in following years
The cars becoming progressively larger, heavier, and more comfortable

The 1969 G.T. 350s and 500s were largely styling modifications to a stock Mustang.
By 1969 Carroll Shelby was no longer involved in the Shelby GT program, and the design was done in-house by Ford.
The 1965 and 1966 G.T. 350s were delivered from Ford’s San Jose assembly plant in body in white form for modification by Carroll Shelby’s operation, originally in Venice Beach and later at Los Angeles International Airport.


All 1965 G.T. 350s were painted Wimbledon White with Guardsman Blue rocker stripes.
Very few GT350s were delivered to the dealer with the optional “Le Mans” (or “LeMans”) top stripes, which run the length of the entire car.
28% of the 562 1965 cars built had Le Mans stripes.
Dealers often added the stripes.
Today, it is difficult to find a GT 350 not so equipped.
Many ERT 1965 cars had the battery relocated to the trunk.
Over-rider traction bars are named so because of their design being on top of the leaf spring as opposed to underneath them.
There was only one transmission available, a 4-speed Borg-Warner T-10 manual.
The exhaust system in the 1965 G.T. 350 was a side-exit dual exhaust with glass-pack mufflers.
The 1965 G.T. 350 had:
A full size spare tire mounted in place of rear seats
Total 1965 model year production was 562 units.

1966 Shelby GT 350

For 1966, the GT 350 lost its Mustang tag and was marketed simply as the Shelby GT 350.
The new model year also saw the introduction of non-white colors, including blue, red, green, and black.
Other changes included:
1. Special rear quarter-panel windows replacing the factory extractor vents
2. Functional brake scoops on each side
3. Optional SelectShift 3-speed automatic
4. Optional Paxton supercharger
The battery was no longer relocated to the trunk for 1966, and the over-rider traction bars were discontinued.
The normal factory fold-down rear seat was optional.
While early 1965 cars had black engine blocks, 1966 and later cars had their engines painted the regular factory Ford dark blue.

The 1966 models came with a dual-exhaust exiting in the rear.
The first 252 GT 350s for 1966 began as 1965 Mustang K-Code Fastbacks.
Total production for 1966 was:
1,373 fastbacks,
This included two prototypes and four drag cars
The 252 early production models with Ford Mustang 1965 bodies
Total production for 1966 was 2,378 units.
A small number of the 1966 models were fitted from the factory with Paxton superchargers, but not the No-Spin limited slip differential; with an option price of $670 USD, the engine was rated at 440 hp (330 kW)

1966 Shelby G.T. 350 Hertz models

Most Hertz cars were black with gold LeMans stripes and rocker panel stripes
A few were white with blue stripes. T
The first 85 Hertz cars were available with:
Four-speed manual transmissions
Hertz advertised them as “Rent-a-Racer” cars.
When the Hertz cars were returned to Ford to be prepared for sale to the public, the high-performance parts were often “lost” (presumably at the manufacturer) before final sale.

1967 Shelby G.T. 350 / G.T. 500

For 1967, the G.T. 350 carried over the K-Code high performance 289 with a ‘COBRA’ aluminum hi-rise.
The G.T. 500 was added to the lineup
It was equipped with a “Ford Cobra” V8 (FE Series 428 engine with two 600 CFM Holly four-barrel carburetors sitting atop a mid-rise Aluminum intake manifold.
Documented plans to introduce a convertible mid-production year were shelved due to supply, production and financial problems
By October 1966, Ford took control over engineering and purchasing.
On August 18, 1967, a small staff were sent to Ionia.
The small staff of the newly formed Shelby Automotive, Inc. had substantially less involvement after this time.
Notable cars for 1967 include:
• The first G.T. 500 built.
• The only Shelby G.T. coupe built (“Little Red’), which was the precursor to the ’68 California Special
• The only Shelby GT 500 convertible built (in 1967)
One 1967 Fastback was updated with a G.T. 500 equipped with a:
427 FE GT40 racing engine producing 650 horsepower
It was known as the “Super Snake”
The car was capable of speeds over 150 mph; hitting 170 mph during a demonstration


For 1968, the Cobra name was applied to both models, and they were now marketed as the Shelby Cobra GT 350 and the Shelby Cobra GT 500.
The solid lifter K-code engine was discontinued by Ford so Shelby used the hydraulic lifter 230 hp 302.
It produced 250 HP with the high rise intake but was not equipped with Shelby headers in order to make room for power steering.
The early 1968 GT500 used the Shelby installed 428 Police Interceptor with a single four barrel carburettor rated at 360 HP.

The initials KR stood for “King of the Road.”
Ford rated the Cobra jet at 335 horsepower (250 kW), but with 440 foot-pounds of torque at 3400 RPM, the horsepower was considered significantly underreported.
