The 1969 Mustang Facts

The 1969 Mustang Facts

1969 was the second major restyle for the Mustang. Every dimension increased with the exception of wheelbase (it remainedat 108 inches) and height, which was lowered by 1 1/2 inches.

Including the two Boss engines, there was a total of ten differentengines available. Headlight configuration for the first time went to four, four-inch units. The fastback body style, called SportsRoof, came with simulated rear side scoops and a spoilered rear. Convertibles and hardtops used a simulated rear quarter panel vent.

The interior was totally restyled, with two separate dash pods available. The standard driver's side pod housed, from left to right,alternator, speedometer, a combination of fuel and temperature,and oil pressure. If the optional tachometer was ordered, it took the place of the fuel and temperature gauges. The temperature gauge was relocated to the far left, displacing the alternator gauge, while the temperature gauge displaced the oil pressure gauge onthe far right.

The Deluxe Interior Group (standard on Mach 1, Grande andBoss 429) came with simulated wood grain appliques on the dash, door panels and console. Numerals on the speedometer (and optional tachometer) were smaller than the standard interior's and the speedometer was divided in multiples of five.

The Interior Decor Group consisted of the molded door panels with woodgrain applique, comfortweave buckets, the Deluxe three-spoke Rim Blow steering wheel and a driver's side remote rectangular mirror. The high-back bucket seats were optional with either interior option. A clock was also housed on the passengerside dash pod.

Instrument face color with the Deluxe Interior Group was dark grey, versus black for standard. This interior was optional only on SportsRoofs and hardtops.

1969 was the last year that bench seats were available and only on the hardtops. Also in 1969, the dual color-keyed race type mirrors were optional on all Mustangs. The Exterior Decor Group consisted of rocker panel moldings,wheel well and rear end moldings.

The GT Equipment Group was still available on all three bodystyles as long as the engine was 351 ci or larger. It consisted of rocker panel GT stripes, GT gas cap, GT hubcaps on styled steel wheels, pin-type hood latches, heavy-duty suspension, simulated hood scoop and chrome quad outlets with dual-exhaust-equipped engines. Only 5,396 Mustangs got this GT option in 1969.

New engines included a 155 hp 250 ci six-cylinder, on which air conditioning was available; Two 351 ci V-8s, basically stretched 302s, joined the lineup. The two-barrel version was rated at 250 hp while the four-barrel was rated 290 hp. These engines were built at Ford's Windsor plant and thus are known as the 351 Windsor or 351W.The 390 was still available, but with a 470 cfm Ford carburetorrather than the previous Holley. A total of 10,494 Mustangs came with the 390.

The 428 Cobra Jet was the top production engine option. Two versions were available, both rated at 335 hp. The non-Ram Air version had the letter "Q" for its engine code, while those equipped with the functional Shaker hood scoop had the letter "R". The Shaker scoop was optional on 351-2V, 351-4V and 390 engines. It was standard with the 428CJ-R.

The optional four-speed manual that was available with the 428CJ was the close ratio version, with a 2.32:1 first gear. All 428s also came with the larger 31 spline rear. 13,193 1969 Mustangs came with the 428CJ.

If a 3.91:1 (code V) or 4.30:1 (code W) rear axle ratio was ordered,the 428CJ was automatically upgraded to Super Cobra Jet(SCJ) status. These engines used special cap screw 427 LeMans type connecting rods, different crankshaft, flywheel and damper, and an external oil cooler mounted in front of the radiator, which reduced oil temperature by 30 degrees. All this for $6.53 - without adoubt the best value option of the year.

Service bulletins on the 428CJ specified that an additional quart of oil be added during an oil change, for a total of six quarts.

The Grande Mustang was a luxury version of the Mustang hardtop. Standard equipment was the Deluxe Decor Group, wire wheel covers, color-keyed dual mirrors, two-tone paint stripes and Grande lettering on each C pilllar.

The rare Mustang E was a specially equipped Mustang SportsRoof designed for economy. It came with the 250 ci six-cylinder, high stall torque converter automatic transmission and a very low, 2.33:1 rear axle ratio. Mustang E lettering on the rear quarters identified the Mustang as such.

The Mach 1 took the place of the GT as the premier performance Mustang. It was based on the SportsRoof and came with along list of standard features. The hood was painted flat black along with a similarly painted non-functional hood scoop. Reflective side and rear stripes were coordinated to complement the body color,as were color-keyed dual racing mirrors. Adding to the racer imagewere the NASCAR hood pin latches, a deleteable option. Chrome styled steel wheels and a chrome pop-open gas cap were also used.The Deluxe Decor Group was used in the interior. Standard engine was the 351-2V. The optional 4V engines came with chrome quad outlets. The Competition Suspension was standard equipment and included staggered rear shocks with the four-speed 428CJs. Standard tires on the Mach 1 were E70xl4s. F7Oxl4 RWL Polyglas tires were mandatory with the 428s.

The limited production Boss 302 was based on the SportsRoof body, but without the simulated side scoops. Flat black paint was used on the hood, headlight buckets, rear deck and taillight panels.A large C side stripe with Boss 302 lettering was used on the sides. Colors were limited to just four: Wimbledon White, Bright Yellow, Calypso Coral and Acapulco Blue. Most Boss 302s came with the standard black Mustang interior, though other colors were optional. A front chin spoiler was standard, while the rear window Sport Slats and rear wing were options. The rear spoiler was plastic on the 1969 Boss 302.

Standard wheels were argent painted 15x7 Magnum 500s using Goodyear F60x15 Polyglas tires. Chrome Magnum 500s were optional. All four fenders on the Boss 302 were radiused so that the tires would not hit.

Other standard Boss 302 features were front disc brakes, quick ratio (16:1) steering, 3.50:1 rear axle ratio and staggered rear shocks.

The Boss 302 engine block was a special strengthened four-bolt main version of the production 302. It used forged steel connecting rods, a forged steel crank and special cylinder heads utilizing2.23-inch (intake) and 1.72-inch (exhaust) valves. An aluminum high-rise intake manifold and a Holley 780 cfm carburetor provide dinduction. All Boss 302 engines came with a mechanical liftercamshaft and a dual-point distributor. All Boss 302s came with afour-speed wide ratio (2.78:1 first gear) manual transmission.

The Boss 3O2s consecutive unit number was stamped on the engine block (at the rear center on a special pad). The Boss 302 andBoss 429 were the only production Mustangs where the original engine block can be matched to the original car.

The Boss 429 Mustang was a limited production Mustang designed to homologate the Boss 429 engine for NASCAR racing. All were built at the Kar Kraft facility in Brighton, Michigan. Partially completed SportsRoof Mustangs that originally were to receive the 428SCJ engine were modified to accept the large 429 engine.The suspension was lowered and moved further outwards one inch, using spindles and control arms unique to the Boss 429. Otherfeatures included Boss 429 fender decals, manually control hood scoop, a front spoiler that was shallower than the Boss 302spoiler, color-keyed dual racing mirrors, engine oil cooler, truck-mounted battery, power steering, power front disc brakes, close ratio four-speed manual transmission, 3.91:1 rear axle with Traction-Lok, 3/4-inch rear sway bar, chrome 15x7 Magnum 500 wheels (long center cap)with F6Oxl5 Goodyear RWL Polygas GT tires, the Deluxe Decor interior, 8000 rpm tachometer and AM radio.

The Boss 429 engine was based on a strengthened version of the production 429. These blocks had HP429 cast into the front of the block (driver's side). It used four-boft mains, a forged steelcrank and forged steel connecting rods. The first 279 engines were tagged 820-S and came with NASCAR-type connecting rods (with 1/2-inch rod bolts) while all subsequent engines were tagged 820-T and used beefed up production rods. Cylinder heads were aluminum and featured a modified hemi-type combustion chamber which Ford called "crescent." These used the "dry-deck" method, meaning no head gaskets were used. Each cylinder, oil passage and water passage had its individual "O" ring to seal it. An aluminum intake manifold with a 735 cfm Holley carburetor provided induction. The camshaft was a hydraulic type. Early engines used magnesium valve covers while later ones were aluminum.

Each Boss 429 Mustang came with a KK sticker placed on the inside of the driver's door above the Ford warranty plate which signified Kar Krafts production number. The first Boss 429 was numbered "KK NASCAR 1201" while the last 1969 was numbered 2059. Some Boss 429s may have this silver tape stripe missing; a small brass plate was substituted by kar Kraft on a small number of cars.

The Boss 429's serial number was stamped on the back side of the engine block assembly, on the inner front fender panels, on the transmission housing and on the chassis itself.

  • 1970 Mustangs were mildly restyled. Headlight configuration reverted to a single seven-inch lamp on each side, this time inside the grille opening, Simulated scoops took the place of the outside headlights. The rear taillight panel was flat rather than concave and the taillights are recessed.

  • While maintaining a basic resemblance to previous Mustangs, the 1971 Mustangs were the largest and heaviest yet. Every dimension increased; Wheelbase was stretched to 109 inches.

    Engine choice still remained high; a total of ten different engines were available on the 1971 Mastang.

    Base engine was the 250 ci six-cylinder on all models except the Mach 1 which came with the 210 hp 302 and the Boss 351 which got a 330 hp version of the 351.

  • Ford Mustangs grew to their all-time largest for the 1971 model year. Wheelbase was up an inch to 109, length increased 2.1 inches to 189.5 and width grew 2.4 to 74.1. The latter was accompanied by a tread increase to allow the 429 cid big-blocks to fit with ease.

    Here's a performance feature that's standard on the BOSS yet not even available on some Trans-AM competitors. a functional front spoiler. This unit helps to keep air out from under the car, make it more stable, cut drag and even increase gas mileage. It's effective at speeds in excess of 40 miles per hour and a real plus when operating on the track


  • It's a pity that Ford didn't document the 1965 through 1969 GT Mustangs with their own unique code, either on the data plate or on the VIN.

  • For 1971, Ford completed its fourth Mustang redesign, creating a bigger car. It had the basic Mustang look, with a longer wheelbase, stretched length, more width, wider front and rear track and heavier curb weight. A raked windshield, bulging front fenders and aerodynamic enhancements were evident.
