For enthusiasts craving mid-engine GM performance, without the C8 Corvette price tag, this 1984 Pontiac Fiero SE could be the perfect alternative. This heavily modified V8 Fiero swapped its factory four-cylinder for a boosted 5.7 Small Block V8 and backs it up with a long list of performance and handling upgrades.

Originally powered by the modest “Iron Duke” 2.5L engine, this Fiero now features a ProCharged Chevy V8 complete with Sportsman Racing Products pistons, GM aluminum cylinder heads, and a TPI Specialties Mini Ram intake manifold. While no dyno numbers are provided, the setup promises serious thrust for such a lightweight mid-engine chassis.

Built for Power and Precision

Transferring that newfound power to the pavement is a 5-speed manual transmission paired with a SPEC Stage 2+ clutch and a limited-slip differential. The car also benefits from an aftermarket exhaust system, coilover suspension, upgraded sway bars, and front brakes sourced from a 1989 Pontiac Grand Am.

The exterior sports a clean white and gray finish, a custom fiberglass rear spoiler, V8Archie side skirts, tinted glass, and 16-inch American Racing wheels. Both front and rear bumpers were updated with 1987 Fiero GT components for a more aggressive look.

A Mid-Engine Chevy We Can Afford

Inside, the cabin features gray and red MrMikes leather upholstery, a Chase Race six-point roll cage, Simpson harnesses, and an array of Autometer gauges. Other upgrades include a Grant steering wheel, faux carbon fiber trim, red carpeting, and an aftermarket CD player. The A/C system has been removed in favor of performance and weight savings.

It’s about time someone took the Silverado and made it the performance truck that GM doesn’t have the cajones to build! That someone is Specialty Vehicle Engineering with their latest creation: a regular cab, short bed Silverado with a supercharged V8 and a 6-speed manual transmission. Right now, if you want a regular cab, short bed V8 pickup, you have to go to Ford. Dodge quit making theirs a few years ago and the current Silverado is only available as a regular cab, long bed with the 5.3 or a regular cab, short bed work truck with the turbo 2.7 as the only option. The last year for a manual-shift Silverado was the 2006 model year.

Bringing Back The Manual Silverado Muscle Truck

When GM introduced the new body styles for the 2019 half-ton trucks, they quit offering a regular cab, short bed V8 package, and that only had the 5.3-liter LT V8. SVE starts with a new a regular cab, short bed work truck with the turbo 2.7 and complete strips it down to convert it to a V8 with a manual transmission, better trim, and other performance and cosmetic upgrades.

A Supercharged 6.8L LT Stroker With Four-Digit Power

Beneath the hood of the latest Yenko/SC Silverado lies a 1,000-horsepower 6.8-liter stroker V8 derived from GM’s 6.2-liter LT architecture. This aluminum powerhouse features a 4.000-inch forged 4340 steel crankshaft with induction-hardened journals, forged steel H-beam connecting rods, and forged aluminum pistons. Feeding the beast is a supercharger engineered by Specialty Vehicle Engineering (SVE), while upgraded injectors and a high-capacity fuel pump ensure the direct-injection system can keep up with the added boost. With CNC-ported cylinder heads and an extra dose of displacement, the result is a street-legal truck delivering four-digit horsepower on standard 93-octane pump gas.

Manual Transmission and Brembo Stopping Power

Transferring that power is a Tremec six speed manual transmission paired with a twin-disc clutch to manage the immense torque without slipping. The truck exhales through a stainless steel dual cat back exhaust, adding an aggressive growl to match its muscle. Braking is handled by Yenko-branded Brembo 6-piston calipers up front, clamping down on massive 16.1 inch rotors for serious stopping power.

Lowered, Locked, and Street-Ready

A lowered suspension setup drops this manual Silverado 2 inches in the front and 5 inches in the rear and is combined with Fox performance shocks, a heavy-duty rear sway bar, much-needed traction bars, and gives the Yenko/SC Silverado a planted, road-hugging stance. It rides on 22×10-inch forged wheels wrapped in Nitto performance rubber, available in several finishes. Buyers can also customize the exterior with various paint colors, Yenko/SC badging, and optional side stripes.

A Pricey but Powerful Throwback to Real Performance Trucks

So what does it cost to own this 1,000-horsepower manual Silverado muscle truck? SVE starts with a base 2026 Silverado 2WD W/T, regular cab, standard bed priced at around ,950. The Yenko/SC conversion adds another ,995, bringing the total to roughly 6,945. That’s a steep price tag, but it’s also the only way to order a 1,000-horsepower, manual-transmission short-bed pickup through authorized GM dealers with a 3-year/36,000-mile limited powertrain warranty to boot. In short, it’s a modern-day muscle truck that turns a humble workhorse into a road-ready weapon no other manufacturer can match.
