General 1966-1977 Bronco information
 
The original Bronco was an ORV (Off-Road Vehicle), intended to compete primarily with Jeep CJ models and the International Harvester Scout(NOTE- This started first as the scout 80 and 800A until the Scout II was introduced in the Spring of 1971). The Bronco's small size riding on a 92-inch (2,337 mm) wheelbase made it popular for off-roading and some other uses, but impractical for such things as towing.

The idea behind the Bronco began with Ford product manager Donald N. Frey, who also conceived of the Ford Mustang; and similarly, Lee Iacocca pushed the idea through into production. In many ways, the Bronco was a more original concept than the Mustang; whereas the Mustang was based upon the Ford Falcon, the Bronco had a frame, suspension, and body that were not shared with any other vehicle.

The Bronco was designed under engineer Paul G. Axelrad. Although the axles and brakes were sourced from the Ford F-100 four wheel drive pickup truck, the front axle was located by radius arms (from the frame near the rear of the transmission forward to the axle) and a lateral track bar, allowing the use of coil springs that gave the Bronco a 34-foot (10.4 m) turning circle, long wheel travel, and an anti-dive geometry which was useful for snowplowing. The rear suspension was more conventional, with leaf springs in a typical Hotchkiss design. A shift-on the-fly Dana Corp. transfer case and locking hubs were standard, and heavy-duty suspension was an option.

The early Broncos were offered in wagon, the ever popular halfcab, and less popular roadster configurations. Roadster was dropped early and the sport package, which later became a model line, was added.

The base price was only US$2,194, but the long option list included front bucket seats, a rear bench seat, a tachometer, and a CB radio, as well as functional items such as a tow bar, an auxiliary gas tank, a power take-off, a snowplow, a winch, and a posthole digger. Aftermarket accessories included campers, overdrive units, and the usual array of wheels, tires, chassis, and engine parts for increased performance.

RACING BRONCO'S

In 1965, racecar builder Bill Stroppe assembled a team of Broncos for long-distance off-road competition for Ford. Partnering with Ford's frequently favored race team Holman-Moody, the Stroppe/Holman/Moody (SHM) Broncos proceeded to dominate the Mint 400, Baja 500, and Mexican 1000 (which was later named the Baja 1000). In 1969 SHM again entered a team of six Broncos in the Baja 1000. In 1971, a "Baja Bronco" package partially derived from Stroppe's design was offered in the Ford showrooms, featuring quick-ratio power steering, automatic transmission, fender flares covering Gates Commando tires, a roll bar, reinforced bumpers, a padded steering wheel, and distinctive red, white, blue, and black paint. However, at a price of US$5,566 versus the standard V8 Bronco price of $3,665, only 650 were sold over the next four years.

In 1966, a Bronco "funny car" built by Doug Nash for the quarter mile dragstrip ran "erratic" with a few low 8-second times, but sidelined by sanctioning organizations when pickups and aluminum frames were outlawed.

1977 the last year of the "Early" Bronco was the only year to have a fuel door instead of the fuel caps.

Engine-
170 I6 modified w/ solid valve lifter, 6 quart oil pan, heavy duty fuel pump, oil bath air cleaner, a carburetor w/ a float bowl compensated against tilting. 105 HP @ 4400 RPM

200 I6 Replaced the 170 in 1973.

289 V8 200 HP

302(windsor) V8 205 HP

Transmission-
The sole transmission was a steering column-mounted, fully synchronized three-speed. (An automatic was not available until 1973, and then only with a 302-cubic-inch V-8.) The three-speed's quick shifting and smooth operation were benefits that had not previously been available in four-wheel-drive vehicles.

Transfer Case-
Prior to the introduction of the automatic transmission, one notch back from neutral engaged two-wheel drive, and a second notch further back set the Bronco in four-wheel drive high. A notch forward of neutral selected four-wheel-drive low range, which could only be engaged when fully stopped.

I haven't been able to locate the "exact" transmission, transfer case, and axles used yet.

What year is your Bronco?

I found this which leads me to believe it was manufactured in August of '76...

BigBlue79 February 4th, 2012 03:00 PM

Hmmm, I don't see an engine code H on any of those years, what engine is in the Bronco?

Raleigh February 4th, 2012 03:04 PM

Yeah , the vin is odd, looks more like a 78/79 vin, but this is in the EB forum? Which is why I asked what year it is.
In the 78/79 H is a 351M.

That was the only reference I could find to that number.

Raleigh February 4th, 2012 03:07 PM

Here we go! Looks like a '79!
