A Decade of Evolution: Understanding the Models (1970-1979)
The 1970s saw a significant transformation in Chevrolet’s truck lineup, offering a diverse range of options for buyers. Understanding these differences is key to finding the right truck for your needs.
1970-1972 C/K Series: The Final Action Line Trucks
These years represent the swansong of Chevrolet’s second-generation C/K series, often referred to as the "Action Line" or "Glamour Pickups." They are characterized by their sleek, integrated styling, particularly the distinctive "egg-crate" grille designs.
- Key Features: Independent front suspension (2WD), coil springs in the rear (2WD), a wide array of engine options (from inline-6s to big-block V8s), and a more car-like ride than previous generations.
- Appeal: Highly prized for their classic good looks and increasingly collectible status. Many prefer these for restoration projects aiming for period correctness.
1973-1979 C/K Series: The Iconic "Square Body"
The introduction of the third-generation C/K trucks in 1973 marked a significant departure from previous designs, ushering in the era of the "Square Body." These trucks were larger, more robust, and boasted improved comfort and aerodynamics.
- Design: Characterized by their strong, angular lines, flat body panels, and a more integrated appearance. This design proved incredibly popular and remained in production, with minor changes, until 1987.
- Nomenclature:
- C-Series: Two-wheel drive (C10, C20, C30 for 1/2-ton, 3/4-ton, 1-ton).
- K-Series: Four-wheel drive (K10, K20, K30).
- Body Styles: Available in various configurations including short bed (SWB), long bed (LWB), Fleetside (smooth sides), Stepside (fenders outside the bed), Crew Cab, and even Dually options.
- Engines: A vast range of engines were offered, including 250 and 292 inline-6s, and a plethora of V8 options: 305, 350, 400 (small block), and the potent 454 (big block).
- Transmissions: Manual options included 3-speed and 4-speed units, while automatics were typically the durable TH350 or TH400.
- Trim Levels: Ranged from basic Custom and Custom Deluxe to more upscale Cheyenne, Cheyenne Super, Scottsdale, and the top-tier Silverado, offering increasing levels of chrome, interior appointments, and creature comforts.
Blazer and Suburban (Full-Size SUVs)
Throughout the 1970s, Chevrolet also offered the full-size K5 Blazer (and its GMC counterpart, the Jimmy) and the spacious Suburban, both built on the C/K truck chassis.
- Blazer: Famous for its removable fiberglass roof (fully removable until mid-1975, then only the rear half), making it a versatile open-air cruiser and off-roader. Highly sought after today, especially early full-convertible models.
- Suburban: The original SUV, offering massive passenger and cargo capacity, ideal for large families or those needing serious hauling power.
Why Buy a 1970-1979 Chevy Truck Today? Benefits and Appeal
The enduring popularity of these trucks isn’t just about nostalgia; it’s rooted in several practical advantages:
- Robust Durability: Built with heavy-gauge steel and simple, robust mechanicals, these trucks were designed to last. Many original components can still be found functioning decades later.
- Unrivaled Parts Availability: Thanks to their massive production numbers and interchangeability of parts across years and models, finding replacement parts is remarkably easy. The aftermarket industry for these trucks is enormous, offering everything from reproduction body panels to modern performance upgrades.
- Customization Potential: The "Square Body" in particular is a favorite for customization. Whether you want to lower it, lift it, swap in a modern LS engine, or build a custom interior, the possibilities are virtually endless.
- Classic Appeal and Appreciating Value: Well-maintained or professionally restored examples are steadily appreciating in value, making them a potentially sound investment. Even driver-quality trucks hold their value well.
- Simplicity of Maintenance: Without complex computer systems or intricate electronics, these trucks are relatively easy for the average enthusiast to work on, fostering a sense of accomplishment and saving on labor costs.
- Versatility: From a work truck to a show truck, an off-road beast to a comfortable cruiser, these trucks can fulfill almost any role.
What to Look For When Buying: Important Considerations and Inspection Tips
Purchasing a vintage truck requires a thorough inspection. While parts are available, extensive repairs can quickly inflate your budget.
- Rust: This is the primary enemy. Common rust spots include:
- Cab: Rocker panels, cab corners, floor pans, firewall, door bottoms.
- Bed: Bed floor, inner and outer wheel wells, bed sides, tailgate.
- Fenders: Lower front and rear sections.
- Frame: Check for pitting, cracks, or signs of improper repair. Pay close attention to areas near suspension mounting points.
- Engine and Drivetrain:
- Cold Start: Listen for excessive smoke (blue for oil, white for coolant), knocking, or unusual noises.
- Fluid Leaks: Check for oil, transmission, coolant, and power steering leaks.
- Transmission: Ensure smooth shifting (manuals) or firm, consistent shifts (automatics) without slipping.
- Driveshaft/U-Joints: Check for excessive play.
- 4WD System (K-series/Blazer): Engage and disengage 4WD to ensure it works properly. Check transfer case for leaks.
- Suspension and Steering:
- Wear: Look for worn bushings, ball joints, tie rod ends, and leaf springs (rear).
- Steering Play: Excessive looseness in the steering wheel indicates worn steering components.
- Brakes:
- Condition: Check brake lines for rust or leaks. Test pedal feel for sponginess or hard spots.
- Discs/Drums: Visual inspection if possible.
- Electrical System: Test all lights, gauges, wipers, heater/AC (if equipped), and radio. Look for frayed or jury-rigged wiring.
- Interior: Assess the condition of the seats, dash pad, door panels, and headliner. While easily replaceable, factor in the cost.
- Documentation: A clear title is essential. Any service records or history can be a big plus.
- Originality vs. Modified: Decide if you want an original truck or one that has been modified. Be wary of poorly executed modifications, which can hide underlying issues. A modified truck might be great, but ensure the work was done professionally.
Restoration, Customization, and Daily Driving: Your Options
Once you acquire your ’70s Chevy, the journey truly begins.
- Full Restoration: For purists, this involves bringing the truck back to its original factory specifications, often involving significant bodywork, paint, engine rebuilds, and sourcing period-correct parts. This is a labor of love and can be expensive.
- Restomod: A popular option that combines vintage aesthetics with modern performance and comfort. This might include an LS engine swap, updated suspension and brakes, air conditioning, and a custom interior. This offers the best of both worlds: classic looks with contemporary drivability.
- Daily Driver: Many ’70s Chevys can be reliable daily drivers, especially with some maintenance and upgrades. Be prepared for lower fuel economy compared to modern vehicles and a lack of modern safety features. However, they offer a unique driving experience and are relatively simple to maintain.
- Project Truck: If you’re on a budget or enjoy wrenching, a project truck can be a rewarding endeavor. Start with a solid frame and cab, and build it up piece by piece.
Challenges and Solutions
While these trucks are fantastic, they do come with their own set of challenges:
- Challenge: Rust:
- Solution: For minor rust, repair panels are available. For extensive rust, full panel replacement or even cab/bed swaps might be necessary. Professional bodywork is often required.
- Challenge: Wear and Tear:
- Solution: Components like suspension bushings, steering linkages, and brake systems will likely need replacement. These are relatively inexpensive and widely available.
- Challenge: Fuel Economy:
- Solution: Older carbureted V8s are thirsty. An LS engine swap (with fuel injection) can dramatically improve efficiency and power.
- Challenge: Safety Features:
- Solution: These trucks lack modern safety features like airbags and ABS. Drive defensively, ensure brakes are in top condition, and consider upgrading to disc brakes all around if not already equipped.
- Challenge: Finding a Good Example:
- Solution: Patience is key. Expand your search radius, use online marketplaces, classic car dealers, and even local classifieds. Be prepared to travel for the right truck.

Q: Can I daily drive a 1970s Chevy truck?
A: Yes, many people do. However, be prepared for lower fuel economy, a less refined ride than modern vehicles, and a lack of modern safety features like airbags and ABS. Regular maintenance is crucial for reliability.

A: Restoration costs vary wildly depending on the truck’s initial condition and the desired level of finish. A full, professional, body-off restoration can easily cost $40,000 to $80,000 or more, in addition to the purchase price of the truck. A driver-quality refresh might be $10,000 to $20,000.
