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.

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.

SMALL BLOCK. BIG ATTITUDE.
450HP from the Smeding 383 Extreme—hard-hitting torque, aggressive idle, and street manners that actually make sense.
This is why it’s one of Smeding’s most popular combos—because it flat-out works.
Power brakes? No problem.
Overdrive trans? Loves it.
Street miles with attitude? That’s exactly what it was built for.
Turn the key. Feel the difference.

THIS ISN’T SUBTLE. THIS IS SUPERCHARGED AUTHORITY.
The Smeding 540 Blown 800HP Big Block doesn’t whisper horsepower—it screams it through an 8-71 blower sticking straight through the hood.
800 tire-shredding horsepower.
Massive 540 cubic inches.
That unmistakable blower whine that turns heads before you even hit the throttle.
Built on a heavy-duty 4-bolt block with forged internals and topped with a billet high-helix supercharger, this isn’t just power—it’s presence. The kind that shoves you into the seat and lets everyone within earshot know exactly what you’re running.
And the best part? It’s built to be streetable… if you’ve got the guts to drive it.
This isn’t for the quiet builds.
This is for the guys who want the hood cut, the blower out, and the whole world watching.
Step up to blown big-block power.

CUSTOM LS CAMSHAFTS—BUILT FOR YOUR COMBO.
The Smeding Performance Custom LS Camshaft isn’t off-the-shelf—it’s spec’d around your engine’s airflow, valvetrain, and goals.
We match the right lobe, not just lift and duration, to maximize real-world power, stability, and usable RPM. Same numbers on paper can act completely different in the engine—this is where it gets dialed in correctly.
Stronger midrange. Better response. More of what your setup is actually capable of.

BIG NUMBERS. CLEAN FOUNDATION. ZERO WEAK LINKS.
The Smeding Performance 441 LS Short Block is exactly what happens when you stop playing around and start building for real power.
4.125 bore. 4.125 stroke. Forged internals. Dart SHP block.
Translation: it’s built to take boost, spray, or all-motor abuse without blinking.
This is the kind of bottom end you build once—and then start planning how much trouble you want to cause with it.
Drop it in, turn it up, and let everything else figure itself out.

THIS ISN’T JUST CUBIC INCHES… IT’S ATTITUDE IN MOTION.
Meet the Smeding Performance 427 Windsor—a small block Ford that refuses to act its size.
Built from a 351 Windsor foundation and punched out to a full 427 cubic inches, this setup doesn’t just nod to the legend—it rewrites it. Lighter than old-school big blocks but packing modern forged internals, it’s the kind of powerplant that turns a street car into a statement piece.
Inside, it’s all business: forged 4340 crank, H-beam rods, 2618 pistons, hydraulic roller cam, and a heavy-duty Smeding block with billet 4-bolt mains. It’s engineered to move air, make torque, and wake the neighborhood without even trying.
What does that translate to? Instant torque. Violent mid-range. And a sound that doesn’t ask permission—it announces arrival.
Drop it into a Mustang, Cobra replica, or full-blown restomod and you’re not just building a car anymore—you’re building something everything else has to respect.
This is the modern 427.
Not nostalgia. Not tribute. Just domination.

427 LS SHORT BLOCK — THIS IS THE HEAVYWEIGHT CUT.
This is 427 cubic inches of LS foundation built to do one thing—hit harder than it has any right to.
It’s not subtle. It’s not trying to be.
It’s the kind of short block you choose when you’re done wondering what “enough power” feels like.
Forged internals. Precision-balanced rotating assembly. Built to take real abuse—boost, nitrous, or high-compression NA setups that don’t lift.
Big cubes don’t ask permission. They just show up early and stay late.
This is the point where the rest of the build stops being important if the foundation isn’t right.
And this one is.
