Chevrolet Cheyenne 1974 Super 10

A 1974 Chevrolet Cheyenne Super 10 laid out over 22-inch wheels that read almost like factory hubcaps is a difficult trick to pull off without losing what made the truck appealing in the first place. This one manages it. Read on for what the Cheyenne Super package actually included in 1974, what was on the engine order sheet, and why clean squarebodies have quietly become expensive.

Dropping a full-size pickup to the ground and stuffing 22-inch wheels under it is one of the easier ways to ruin a good truck. The proportions of a 1970s Chevrolet were never drawn with that stance in mind, and most attempts end up looking like a compromise between two ideas that do not want to share a driveway. This one does not. The wheels read almost like painted steel and a set of factory caps at a glance, the ride height looks deliberate rather than fashionable, and none of the original character has been sanded off in the process. What is worth remembering is that underneath the stance sits a truck that was ordered as serious working equipment.

The Generation That Changed What a Pickup Was

The 1974 model sits inside the third-generation C/K line that Chevrolet launched for 1973 and built through 1987, the trucks enthusiasts universally call squarebodies. General Motors internally referred to the styling as the Rounded-Line, and the redesign was genuinely ambitious for a work vehicle. It brought curved side glass, a substantially roomier cab, double-wall bed construction, and aerodynamic development that was unusual for the category at the time. The result was a pickup that could plausibly serve as a family vehicle rather than strictly as a tool, which is a large part of why the platform stayed in production for fifteen years with relatively modest changes.

What the Cheyenne Super Badge Actually Bought

Cheyenne Super sat at the top of the 1974 trim hierarchy, above Custom Deluxe and standard Cheyenne. Ordering it brought woodgrain appliques across the dash and door panels, carpeting in place of a rubber floor mat, additional sound insulation, brighter exterior trim, a fuller instrument package and upgraded seat upholstery. In a segment where most buyers were still specifying rubber floors and a bench seat, it represented a genuine luxury option. The Super 10 designation identifies it as a half-ton, the C10 chassis, wearing that top trim rather than a heavier-duty three-quarter or one-ton configuration.

The Engine Order Sheet in 1974

A buyer could start with the 250 cubic-inch inline six for light duty, step up to the larger 292 six, or move into V8 territory with the 350 small-block. For anyone genuinely planning to tow, the 454 cubic-inch big-block was available and remains the engine most sought after in these trucks today. The 305 small-block that later became common across GM’s lineup had not yet reached the truck range in 1974. Notably, 1974 was also the last model year before catalytic converters and unleaded fuel requirements arrived, which is one reason this specific year holds a slight premium with some buyers.

A Truck Built in the Middle of a Fuel Crisis

The 1973 oil embargo landed directly on top of this generation’s launch, and the timing shaped what was actually sold. Big-block orders fell away sharply as fuel prices climbed, pushing volume toward the sixes and the 350. That matters now because it makes an original 454-equipped Cheyenne Super meaningfully rarer than the production totals for the generation would suggest. It also explains why so many surviving examples have been re-engined over the decades, with the original drivetrain long gone and something more modern sitting between the fenders.

Why Getting a Squarebody This Low Is Hard

Laying a full-size truck out this far is not a matter of cutting coil springs and adding lowering blocks. Once the frame approaches the pavement, suspension geometry stops working the way it was designed to, and correcting it usually means relocating control arm mounting points, addressing steering geometry to eliminate bump steer, and in many builds notching the frame so the rear axle has anywhere to travel. Brake lines, fuel lines, and the exhaust all have to be rerouted. Done badly, the truck rides on its bump stops and becomes miserable within a mile. Done properly, as here, it retains real suspension travel at a ride height that looks impossible.

The Wheel Choice That Makes This Build Work

The detail that separates this truck from most is the wheel selection. Choosing a 22-inch wheel with a face that reads like a period-correct cap keeps the eye from immediately registering a modern aftermarket component. That restraint is what allows the build to feel like an evolution of the original design rather than a costume placed over it. It also solves a practical problem, because a larger wheel is often necessary to clear big brake hardware and to fill the wheel well once the truck is sitting this low. The alternative, a smaller wheel with a stretched tire, tends to look visually undernourished on a body this large.

From Farm Equipment to Auction Fodder

For most of their lives these trucks were consumables. They hauled hay, carried tools, sat outside through decades of winters, and were replaced without ceremony when the sheet metal gave out. That treatment is precisely why clean, rust-free, unmolested examples are now genuinely scarce, and values have followed. Squarebody Chevrolets and GMCs have climbed sharply in the collector market over the past decade, with well-sorted trucks routinely clearing figures that would have seemed absurd to anyone who bought one new to work a ranch with.

The Rust That Ends Most of These Projects

Anyone shopping for a squarebody to build should know where these trucks fail. The cab corners, the rocker panels, the lower front fenders behind the wheel openings and the floor pans under the seat are the usual casualties, and on trucks that spent time in salted states the cab mounts themselves can be gone entirely. Bed sides and the front of the bed floor are close behind. Reproduction sheet metal is widely available and reasonably priced, which is one reason the platform has become so popular to build, but replacing structural cab metal properly is bodywork of a different order than bolting on a fender. It is the single largest hidden cost in a project like this one.

Where the Custom Truck Scene Went

This build sits in a tradition that runs from the mini-truck movement of the 1980s through today’s C10 scene, where the objective is to make a working vehicle handle and ride like a modern car while looking like it rolled off the line and simply settled. Air suspension, coilover conversions, rack and pinion steering, disc brakes and LS engine swaps have all become standard vocabulary. The best examples, this one included, hide most of that work. The trick is not the parts list, it is having the discipline to leave the truck looking like itself once the parts are installed.
