Model: C10

As the humble pickup truck's place in American culture steadily evolved from simple-but-valued tool to modern fashion statement, it gained a huge fan base. While admiration grew and trucks aged, restorers began returning some of them to showroom shape. Meanwhile, hot-rodders and customizers crafted their own interpretations of the classic pickup.

The years rolled on and certain models emerged as favorites, spawning a vast aftermarket blooming with reproduction and upgrade parts and kits. So widespread is this enthusiasm for classic pickups today that values of the most popular models have swelled substantially during the past decade or so. It's good news if you already have one, but not so great for anyone on the hunt for a budget-friendly alternative to pony cars or muscle machines.

This 1997 C1500 short-bed Fleetside was located in the Carolinas and hauled north to Vermont, where 1967-'72 Chevy truck enthusiast Glen Sauer picked it up for short money as a low-budget project to build with his son. It had essentially zero rust, but a worn and baked interior and over 200,000 miles.

Consider the 1967-'72 Chevrolet trucks, popular from new and long adored by enthusiasts. Today, they're nearly as sought after as the muscle cars of the same era, and values have followed suit, making them less accessible to the younger builders trying to get into a vintage project. More recently, the following generation of Chevy trucks— the 1973-'87 "square-body" era—has been following the same trajectory, with values escalating rapidly.

So, where does that leave the aspiring young builder on a budget? Or even the seasoned tinkerer looking to start a new project with a casual cash commitment? Fortunately, GM kept right on building pickups, and its next generation proved to be a winner.

This truck left the factory with a blue cloth interior, but after more than 20 years and many miles worth of service, along with years spent under the southern sun, it was showing its age. Plus, a blue interior didn't suit Glen's taste for this project, so this will all be removed.

The familiar Chevy small-block V-8 powered most GM ½-ton trucks of the 1988-'98 period. Beginning with the 1996 model year, GM used the Vortec version of its 5.7-liter V-8, with improved cylinder heads and updated fuel injection. This one was rated for 255 hp, and even with more than 200,000 on the odometer, it still runs just fine. Apart from basic maintenance items, they're going to leave it alone for now.

For the 1988 model year, GM introduced a new line of light trucks under the internal designation "GMT 400." To the public, the new generation of trucks was often referred to as the "C/K" series, combining the familiar C designation of two-wheel-drive models with the K of 4x4s. The new C/K line offered increased interior space, while appearing leaner and more svelte on the outside thanks to a "cab forward" design with a sloping hood and rounded prow. This was the first time GM had offered extended-cab variations on its pickups, and the traditional "step-side" bed was finally replaced with a new fiberglass Sportside interpretation.

Viewed today, the GMT-400 era of trucks was an excellent blend of then-modern technology merged with traditional pickup dimensions. Though some details are very of-the-period, like the mini quad headlamps of the earlier models and the plasticky dark-argent egg-crate grilles, GM's stylists smoothed out many of the trim details as the generation evolved, and overall these trucks have aged well. Park a GMT 400 next to a 1967-'68 Chevy pickup and you might even wonder if GM's stylists looked back for inspiration.

In the process of getting this project rolling, Glen came across two parts trucks for around $300 apiece. The crew cab 3500 was wrecked and had already given up its 454 and 4L80E transmission, but had lots of good interior bits to contribute. The green 1500 had many more gray interior parts for the cause, plus a manual five-speed. Both trucks were later sold for parts/scrap, yielding a net-zero investment.

All GMT-400 trucks left the factory with electronic fuel injection of some sort, they all had front disc brakes, and the vast majority had transmissions featuring overdrive, whether automatic or manual. The GMT-400 trucks were engineered to hold the road like no trucks that had come before.

Today, those features, and the C/K's relatively trim size (compared to contemporary full-size pickups), make these trucks great drivers. Plus, since these are often cited as the generation of pickups that launched the full-size sport-truck movement, the aftermarket is teeming with parts. They've even picked up their own nickname: "OBS," for old body style.

The green parts truck was heavily rotted, but its interior was in great shape other than needing a thorough cleaning. Glen will use the cloth and vinyl split bench for now, plus lots of the dash parts and the manual-transmission instrument cluster.

But perhaps best of all, the 1988-'98 GM C/K trucks are affordable and readily available, making them perfect project fodder. That's what one of our local friends, Glen Sauer, realized when he was looking for a new truck project for his young son. Glen is a longtime fan of the 1967-'72 Chevy trucks, having built several over the past 30-some-odd years since he started as a teen; he's got another going together right now. That's how he knew it wouldn't be feasible to get another example from that period to serve as a fun fixer-upper that could also provide legitimate transportation on a short budget.

However, when a friend came up from the Carolinas with a pair of '97 Chevy C1500 short-beds, Glen knew he'd found his next project. The one he bought is the classic sport-truck builder's favorite: a short-bed Fleetside with a standard cab and two-wheel drive.

Glen wants the project truck to have a manual gearbox instead of its factory-issued automatic. The two-wheel-drive 1500 parts truck's manual five-speed arrangement is just what they need to convert the short-bed to stick. In addition to the transmission itself, Glen took the pedal set, steering column, hydraulic clutch setup, driveshaft, and other associated parts needed for a factory-appearing conversion.

"I probably paid all the money for this thing, but it was so clean I didn't mind," Glen says of the purchase. But for one of these trucks right now, "all the money" was still less than $6,500, and it runs, drives, and even has decent paint. Living in Vermont, Glen is painfully familiar with the effects of long winters and the heavy doses of road salt that accompany them. Typical OBS Chevy trucks from this area are now significantly rotted, their chassis often heavily scaled and held together with fasteners that are all fused from corrosion. But the '97 from the South hasn't the slightest trace of that.

"It's got a lot of miles, and the interior was whooped, but I'm not worried about any of that," offers Glen. The drivetrain in this truck is the 5.7-liter Vortec V-8, which Chevy started using the model year prior. This was the engine that got the updated "fast-burn" cylinder heads that became popular with hot rodders soon after, for the components' performance and low cost. The engine is backed up by the 4L60E four-speed automatic. Both seem to function just as they should in spite of the more than 200,000 miles showing on the odometer.

The five-speed gearbox used in ½-ton trucks of this vintage is the NV3500. It has overdrive in fifth gear, but also has a low first gear. It's a smooth-shifting unit, and though not intended for high performance, it should still make this truck more fun to drive.

The restoration parts aftermarket for the OBS is still in its infancy, but that's okay for now—those rusty northeastern trucks all around us make excellent interior donors for the dried-out southern and western examples. Glen's been picking through area junkyards for some of the items needed, but then came up with two different parts trucks. Each one provided lots of interior bits and some other trim, but one of them also had another key contribution.

"I really want this truck to have a manual gearbox," Glen says. "For one, it's just cooler, but I also want my son to have his hands full when he starts driving—if he's got the steering wheel in one hand and the shifter in the other, he won't be able to mess around with his phone while he's driving."

In addition to being the wrong color, the project truck's blue dash was extensively cracked and broken from sun damage. After it was removed, it was put on the bench along with a gray dash from one of the parts trucks to make some component and wiring harness transfers.

Interesting logic, and a plan that the second parts truck will facilitate by providing a complete two-wheel-drive, five-speed-manual setup. In addition to the gearbox itself, Glen scavenged the pedal set, steering column, hydraulic clutch linkage, floor boot, transmission crossmember, driveshaft, and even the wiring harness and powertrain control module.

That truck also had a good gray interior, which is what Glen wanted to replace the worn-out stuff the '97 came with—the blue gut on a white truck isn't his style anyway. For now, the used interior will be cleaned, patched by a local upholster as needed, and pressed back into service. Down the road, when the budget allows, another set of donor buckets will be reupholstered in aftermarket leather covers. The gray dash from a donor is also being swapped over, and a good salvaged headliner "card" has already been covered in factory-style gray cloth.

At this point, the blue interior has already been banished and the gray dash is in place. A new factory-style carpet is on order, and they're getting all the pieces ready to put this back together to look like it rolled of the line with a gray interior and a five-speed stick. Next month, we'll detail the interior makeover.

Here's another aspect of the OBS trucks we hadn't counted on: The two parts trucks—the five-speed C1500 extended cab and a C3500 1-ton crew cab that was wrecked, rotten, and already relieved of its big-block and 4L80E automatic—have both been sold off after being plucked, for more than Glen had paid for them. That means all of the scavenged parts were essentially free. You can't do that with a 1967-'72 anymore.

The first order of business is to swap the interior, including the manual transmission's pedals and steering column—we'll detail that in next month's issue. Then we'll follow up with the five-speed swap, and finally, some new wheels and tires and a little suspension updating to yield a cool, low-buck daily-driver Chevy pickup.

Mazda Miata Could Have Competition: Toyota is Going Full Send with its S-FR Sports Car
Toyota

Toyota is pulling out all the stops to compete with the likes of affordable sports cars like the Mazda Miata. The automaker reportedly plans to put the S-FR concept car, originally debuted in 2015, into production. With potential release dates slated for early-2026 or early-2027, perhaps Miata may not always be the answer.

A new report out of Japan confirmed that the Toyota S-FR concept, first seen at the 2015 Tokyo Motor Show, will hit the market to challenge the entry-level sports car segment. Forbes backs up this claim via its print edition of Best Car. According to the report, the Toyota S-FR will be produced in partnership with Daihatsu, a wholly owned subsidiary of Toyota, and Suzuki, of which the Toyota Motor Corporation owns 4.94 percent.

1978 Aston Martin V8 Series 3, front quarter

What if I told you that not all muscle cars are from Detroit? No, I’m not talking about any of the rebellious machines from Kenosha. I’m talking about Newport Pagnell. Where exactly is Newport Pagnell you ask? It’s about 50 miles northwest of London, and the traditional home of Aston Martin, where thousands of its cars were built between the mid-1950s through 2007. Let’s take a look at this 1978 Aston Martin V8 Series 3 currently offered on Hemmings Auctions as a prime example of a non-Detroit muscle car.

How does the AMV8 stack up as a muscle car? Let’s count the ways: It’s got a booming, high-performance V8 under the hood that sends power to the rear wheels—and the rear wheels only. It’s a two-door coupe with a long hood and a fastback roof. It has a big hood scoop needed to clear a quartet of Weber two-barrel carburetors. It even has a Chrysler TorqueFlite automatic transmission for that authentic Yankee feel.
