Mechanical Specifications and Performance of the 1987 Chevrolet Blazer

Engine Options and Powertrain Characteristics

The 2.8L V6 (L05) produced 125 horsepower (SAE net) at 4,400 RPM and 165 lb-ft of torque at 2,400 RPM. This engine was paired exclusively with a 2-barrel carburetor (Rochester 2GC), limiting its throttle response and fuel efficiency compared to fuel-injected alternatives. Real-world performance figures placed the 0-60 mph acceleration around 13–15 seconds, with a top speed capped at approximately 95 mph due to gearing. Fuel economy averaged 16–18 MPG city / 20–22 MPG highway (2WD) and 15–17 MPG city / 18–20 MPG highway (4WD), aligning with EPA estimates for the period.

The 2.5L inline-4 (Tech IV), introduced in the Blazer II, generated 90 horsepower (SAE net) at 4,000 RPM and 130 lb-ft of torque at 2,000 RPM. This engine was available with either a single-point fuel injection (TBI) or a 2-barrel carburetor (Rochester 2GC), with the TBI version offering marginally better throttle linearity and slightly improved fuel economy. The inline-4’s lower power output translated to 0-60 mph times of 16–18 seconds, with a top speed near 85 mph. Fuel economy was marginally superior, with 17–19 MPG city / 21–23 MPG highway (2WD) and 16–18 MPG city / 19–21 MPG highway (4WD).

Note on Fuel Delivery Systems:
The 1987 Blazer’s carbureted engines suffered from cold-start reliability issues and inconsistent air-fuel mixtures under load, while the TBI system (where available) reduced emissions but introduced new challenges, such as vacuum leaks and sensor failures. The lack of multi-point fuel injection—a standard in contemporary cars—limited both performance and efficiency.

Transmission and Drivetrain Configurations

Gear ratios varied by transmission type and drivetrain configuration:

- Automatic Transmission (3-speed):

The 4WD system utilized a part-time transfer case with a 2-speed transfer case (low and high range), allowing drivers to engage 4WD in high range for on-road use or low range for severe off-roading. The transfer case could be shifted on the move in high range but required the vehicle to be stationary in low range. A viscous coupling (in some models) provided limited 4WD engagement without manual intervention, though this was less reliable than the traditional transfer case.

Drivetrain Quirks:
The 1987 Blazer’s 4WD system lacked a center differential lock, a common omission in SUVs of the era, which reduced off-road capability in loose terrain. Additionally, the transfer case’s low-range engagement was often sluggish, and the automatic transmission’s torque converter could struggle with the higher torque demands of low-range 4WD, leading to premature wear.

Handling and Off-Road Capabilities

On-road handling was characterized by body roll due to the Blazer’s high center of gravity and soft suspension tuning, which prioritized comfort over cornering precision. The steering ratio of 16.3:1 provided adequate feedback but lacked the quickness of modern SUVs. Braking was handled by drum brakes on all wheels, with optional disc brakes on the front in higher trims, offering marginal improvements in stopping power.

In off-road scenarios, the Blazer’s ground clearance of 8.2 inches was adequate for light trails but insufficient for rock crawling or deep mud compared to the Jeep Cherokee’s 8.8-inch clearance or the Ford Bronco II’s 9.5-inch clearance. The lack of a locking rear differential further limited its off-road prowess, as wheel spin was common in loose conditions. The S-10-based Blazer II improved slightly with its independent front suspension (IFS), reducing body roll and enhancing on-road manners, though it retained the same rear solid axle.

Comparison to Contemporaries:

Jeep Cherokee (XJ): Superior approach/departure angles, solid front axle, and optional locking differentials made it the benchmark for off-road SUVs. However, its 4.0L inline-6 engine provided more power at the expense of fuel economy.

Ford Bronco II: Shared the Blazer’s body-on-frame design but offered a more robust suspension and optional locking rear differential. Its 2.9L V6 provided better performance, though reliability was a concern.

Toyota 4Runner (First Generation): While not yet available in the U.S. in 1987, its rigid body structure and 4WD system would later set a new standard for longevity and off-road capability.

Common Mechanical Issues and Troubleshooting
