The End of an Era: Why 1986-87 Square Bodies Stand Out

The Square Body generation of Chevrolet C/K trucks ran from 1973 to 1987, earning its nickname from its distinctive, angular styling. Over its long production run, it saw numerous improvements and variations. The 1986 and 1987 models represent the final, most refined versions of this design, just before the introduction of the GMT400 platform.

What sets the ’86 and ’87 models apart?

• Refined Design: By this point, most of the kinks from the earlier years had been worked out, and the trucks offered a comfortable, albeit utilitarian, interior with classic lines.
• Mechanical Simplicity: While 1987 saw the introduction of Throttle Body Injection (TBI) for some engines (like the 5.7L V8), many ’86 and even early ’87 models retained carbureted engines. This often means easier diagnosis and repair for the DIY mechanic, though TBI offers better cold starts and efficiency.
• Versatility: These trucks were available in a vast array of configurations:
  • C/K Nomenclature: ‘C’ denotes two-wheel drive (2WD), and ‘K’ denotes four-wheel drive (4WD).
  • Wheelbase/Bed Lengths: Short bed (117.5" wheelbase), long bed (131.5" wheelbase).
  • Cab Styles: Regular cab, Extended Cab (Crew Cab models were also available but less common in later years).
  • SUVs: The platform also underpinned the full-size Chevrolet Blazer (K5) and Suburban, offering enclosed utility vehicle options.

  

• Trim Levels: Common trims included Scottsdale (base), Cheyenne (mid-range), and Silverado (top-tier), each offering different levels of interior comfort and exterior brightwork.

This combination of classic looks, robust construction, and relatively simple mechanics makes the 1986-87 Square Body a highly sought-after vehicle today, appealing to both purists and those looking for a capable vintage truck.

Engine & Powertrain Options

A significant part of the Square Body’s appeal lies in its straightforward and durable powertrains. Understanding the options available in 1986-87 is crucial for potential buyers.

Engines:

• 4.3L (262 cu in) V6: Standard in many half-ton C/K models, offering decent power for lighter duties and slightly better fuel economy than the V8s.
• 5.0L (305 cu in) V8: A popular option, providing a good balance of power and economy. Many were carbureted, but some 1987 models started receiving TBI.
• 5.7L (350 cu in) V8: The workhorse of the lineup. In 1986, it was primarily carbureted. For 1987, the 350 V8 in light-duty trucks was the first to receive TBI, a significant upgrade for performance and reliability. This is often the most desirable engine for its power, parts availability, and upgrade potential.
• 6.2L (379 cu in) Diesel V8: A naturally aspirated diesel option, known for its longevity and fuel efficiency (for its time) but often criticized for its lack of power compared to the gasoline V8s. Good for towing at lower speeds.

Transmissions:

• Automatic:
  • TH350 (Turbo Hydra-Matic 350): A durable 3-speed automatic, common in earlier Square Bodies and some 1986 models.
  • TH400 (Turbo Hydra-Matic 400): A heavy-duty 3-speed automatic, typically found with larger engines or in heavy-duty applications.
  • 700R4 (Turbo Hydra-Matic 700R4): A 4-speed automatic with an overdrive gear, standard on most light-duty trucks in 1986-87. This is generally preferred for highway driving due to better fuel economy at speed.
• Manual:
  • SM465 (Saginaw Muncie 465): A robust 4-speed manual transmission, known for its very low "granny" first gear, excellent for heavy loads or off-road use.

Key Consideration: The choice between carbureted and TBI engines in 1987 is significant. TBI offers easier cold starts, better idle quality, and often improved fuel economy and emissions. However, carbureted systems are simpler to diagnose and repair for those with old-school mechanical skills.
