How much horsepower does a 78 Bronco have?
On a 1978 Bronco, horsepower isn’t a single fixed figure. The output depended on which V8 engine the vehicle came with, and whether it used a two-barrel or four-barrel carburetor. Factory ratings for that year generally fall in a broad range—from roughly 150 horsepower up to just over 210 horsepower depending on the configuration.
Engine options and horsepower
The 1978 Bronco offered multiple V8 options, with horsepower figures differing by carburetion and emission controls. Here are the main factory choices and their approximate, era-era SAE net horsepower ranges:
- 302 cubic inch V8 (5.0 L): about 150–170 hp with a two-barrel carburetor; roughly 210 hp with a four-barrel setup.
- 351 Windsor V8 (5.8 L): about 170–190 hp with a two-barrel carburetor; around 210–230 hp with a four-barrel configuration.
- 351M V8 (5.8 L): roughly 160–190 hp with a two-barrel carburetor; about 200–210 hp with a four-barrel.
In practice, the exact number for any given 1978 Bronco depends on the original engine option, emission equipment, and whether the vehicle is a factory stock example or has been reworked. For an accurate figure, check the original build sheet or the VIN/engine code on the specific truck.
Performance context and what to expect
Horsepower is only part of the picture. The Bronco’s performance in 1978 was shaped by its curb weight, the chosen transmission (manual or automatic), gearing, and the use of off-road hardware. Even at the higher end of the horsepower range, a 1978 Bronco remains a classic SUV with modest acceleration by modern standards, but strong torque for off-road work and towing capability when properly equipped.
Owners and restorers who aim for a more spirited drive often maintain or swap in the higher-output 4-barrel variants or opt for modern fuel-injection swaps, which can improve throttle response and drivability while keeping the vehicle’s vintage character. Always verify the exact engine configuration before quoting horsepower numbers for a specific Bronco.
Summary
The 1978 Ford Bronco offered several V8 engines, so horsepower ranged roughly from 150 to 210+ hp depending on engine type, carburetion, and emissions equipment. To know the precise figure for a particular Bronco, refer to its original build documentation or engine code.
How much horsepower does a 1978 Ford 302 have?
The 1978 Ford 302 engine produced approximately 140 horsepower in its most common two-barrel carburetor configuration, a result of reduced compression and power-robbing emissions controls of the era. This was a period of lower horsepower ratings for the 302 compared to earlier versions.
- SAE Net Rating: The most common version of the 1978 302 with a two-barrel carburetor was rated at 140 net horsepower (104 kW).
- Reasons for low power: This low output was due to factors like a two-barrel carburetor, lower compression ratios, and government-mandated emissions equipment that choked performance.
- Comparison to earlier models: This was a significant drop from earlier 302 engines, some of which were rated at over 200 hp (gross) in the late 1960s and early 1970s.
- Other variations: While 140 hp was the standard, some versions or specific applications might have had slightly different ratings, but the 140 hp figure is the most representative for a typical 1978 application, notes www.mustangspecs.com.
