S10 V8 Engine Swap, Part 1
From the crew at StreetTrucks.com
It’s no secret that the Chevy S-10 is one of the most popular minis in our scene to cut up and lay flat on the ground. For many of us it’s also the daily driver that gets us from Point A to Point B, unfortunately it came from the factory with a puny little four-cylinder or an equally unimpressive six-cylinder engine that tends to have a hard time getting out of its own way.
While a V-8 swap isn’t entirely rare in the second generation S-10s, it’s never been easier to accomplish thanks to Stylin’ Trucks and their new line of GM crate motors as well as transmissions and accessories. Their one-stop shopping experience removes the hassles of hunting down parts by placing everything within a few clicks on your computer.
Some may take the “bigger is better” approach when doing a motor swap in their truck, but with today’s gas prices at an all time high that may not be the most economical strategy. Stylin’ Trucks carries up to the 383-stroker motors if that’s your poison, but they also carry several more fuel-efficient GM crate motors.
The project that we’ve selected for a motor swap is our ’97 S-10. Our approach to this won’t be huge horsepower and quarter-mile times though, for this project we’re going to shoot for fuel economy and freeway cruising. This is, after all, a California cruiser that will see plenty of SoCal highways over the next few years.
In order to achieve our desired fuel economy we’ve chosen a modest 5.7L crate engine from the Stylin’ Trucks Web site, but we’re going to mate it with some goodies like electronic fuel injection and an overdrive transmission. These components will combine to increase the overall fuel economy.
The GM crate engine (P/N 10067353) features a four-bolt main and two-piece rear main seal. A modest 8.5:1 compression and mild cam net approximately 260 HP from this GM block. We’ll be mating it to a Street Fighter 700R4 transmission from TCI, which provides the convenience of an overdrive automatic transmission for our highway runner.
Topping off our block is the Thruster electronic fuel injection system from Accel. This system is designed to work with a wide variety of engines that range from mild to wild and includes a fuel injection system and wide band O2 sensors as well as all of the necessary wiring harnesses. The Accel EFI is laptop programmable and promises unmatched drivability for our S-10 project.
Within the next few issues we will document the step-by-step process of removing the puny four-cylinder that is currently inhabiting our engine bay and replacing it with the 5.7L GM performance crate engine. For now we’ll leave you with a preview of the parts we will use in the upcoming V-8 engine swap.
Stay tuned for future stories as the crew at StreetTrucks Magazine begin pulling out the sorry four-cylinder and swapping in the new 5.7L V-8 and additional components.
