Some engines make horsepower.
A 406 makes a statement. ⚡

The Smeding Performance 406 Long Block was built for the kind of hot rodder who still wants a car to feel a little dangerous. The kind of engine that rocks the fenders at idle, fogs the tires on command, and sounds downright pi**ed off every time the throttle cracks open. 😈

This isn’t some fragile dyno hero built to chase numbers on a screen. This is real-deal street and strip muscle — forged internals, aluminum heads, hydraulic roller power, and enough torque to make a lightweight Chevy feel absolutely unhinged.

Drop this thing into a Chevelle, Nova, Camaro, or C10 and suddenly every gas station stop turns into a crowd. Every tunnel becomes mandatory full throttle. Every guy in the next lane starts wondering if he made a mistake pulling up beside you.

Because a nasty small block with cubic inches and attitude never goes out of style. 💀

You don’t build a 427 because you want decent power.
You build a 427 because 350s stopped scaring you years ago.

Whether you’re putting together a tire-annihilating street car, a nasty Pro Touring build, or a strip bruiser that shakes the grandstands at idle, this short block is ready to handle the violence. Add your top end combo, feed it air and fuel, and let the torque do the talking.

💥 4340 forged rotating assembly
💥 Dart SHP 4-bolt block
💥 Hydraulic roller cam options up to 560HP
💥 Built for boost, spray, or pure cubic-inch attitude
💥 The kind of torque that makes passengers grab the dash

Big cubes. Big noise. Big problem for the guy in the next lane. ⚡

420 horsepower. Street manners. Tire-shredding torque. That’s the sweet spot. 🔥

The Smeding Performance 383 Hot Rod 420HP was built for guys who want brutal small block power without sacrificing drivability. This isn’t some peaky dyno queen that hates traffic lights and vacuum accessories. This is the kind of stroker that lights the tires, rattles the windows, and still cruises highway miles like a champ. 💪

With a hydraulic roller cam, aluminum heads, forged internals, and dyno-tested reliability, this 383 delivers the kind of broad torque curve that makes every stab of the throttle feel violent in the best possible way. Drop it in your Camaro, Chevelle, C10, Nova, or street rod and get ready for that deep, nasty idle everybody turns around to hear. 😈

🔥 420HP
🔥 Massive street torque
🔥 Pump gas friendly
🔥 Dyno tested before it ships
🔥 Built to run hard and live long

This is the heartbeat your hot rod’s been missing.

REMEMBER & HONOR.

In observance of Memorial Day, Smeding Performance will be closed Monday as we take time to honor those who gave everything in service to our country.

As this weekend approaches, and while the shop will pause operations, our respect and gratitude never do. We remember the heroes who made the ultimate sacrifice, and we honor the families who carry their legacy forward.

From all of us at Smeding Performance — we remember. We honor.

Some people want reliable.
Some people want fuel mileage.
This one’s for the guys who want to make the dyno operator nervous.

The Smeding Performance 441 LS7 Short Block is pure heavyweight LS aggression — packed with forged hardware, a Dart SHP block, and enough strength to handle the kind of boost levels that make stock blocks split in half. This isn’t your buddy’s junkyard 5.3 build. This is big-inch, tire-annihilating, track-shaking violence waiting for turbos, nitrous, or your right foot.

Built for the people who think “too much horsepower” sounds like quitter talk.

427 cubic inches of Ford fury.

Whether you’re building a nasty street bruiser, drag car, or boosted weekend weapon, this short block gives you the foundation to build horsepower your way. Big-inch Windsor power with the strength to back it up. No gimmicks. No fluff. Just pure Ford muscle waiting for boost, RPM, and tire smoke.

427 cubic inches. Forged internals. Hydraulic roller cam. Aluminum heads.
This isn’t some catalog crate motor built to cruise to the grocery store. The Smeding Performance 427 SBC Long Block is built to hit hard, pull hard, and sound absolutely violent doing it. With up to 560 horsepower on tap and a fully forged rotating assembly, this small-block delivers big-block attitude without the extra weight.

From street machines to pro touring builds and nasty weekend bruisers, this 427 is the kind of powerplant that changes the whole personality of a car the second you stab the throttle. Big cubes. Instant torque. Zero apologies.
