Not every big-block build needs to be a wild animal. Sometimes you just want to turn the key, hit the road, and have enough power to embarrass almost anything that pulls up next to you.

The Smeding Performance 540 Cruiser delivers exactly that. Massive big-block torque, a healthy 620 horsepower, and the kind of effortless acceleration that makes every on-ramp feel like an event. It's built for drivers who want serious muscle without sacrificing reliability, drivability, or weekend road-trip comfort.

Because cruising is a lot more fun when you've got 540 cubic inches under your right foot.

🔥 What's going in your dream cruiser—a Chevelle, Camaro, Nova, C10, or something else?

There's big-block power... and then there's 572 cubic inches of pure intimidation.

The Smeding Performance 572 Extreme isn't built for subtlety. With over 700 horsepower and 700 lb-ft of torque on pump gas, this beast delivers the kind of tire-frying, neck-snapping acceleration that makes passengers grab the dash and spectators stop what they're doing. Every engine is hand-assembled, dyno-tested, and built to unleash serious street and strip attitude.

If your idea of "enough power" starts with a 7, this is your engine.

🔥 What would you drop a 700+ horsepower 572 into?

Got a rectangle-port LS that's begging for more attitude?

Smeding Performance Rectangle Port Cams deliver the sound, power, and seat-of-the-pants excitement that makes every drive worth taking. Whether you're cruising Main Street, ripping through the gears, or making noise at the local cruise-in, these cams bring the chop, the throttle response, and the grin that comes with serious LS performance.

Because stock is boring.

🔥 How rowdy is your LS build?

Two Smeding Performance 572" Blown 900HP engine packages are heading out the door and ready for their next chapter.

Seeing one big-block leave the shop is always exciting, but seeing a pair of these powerhouses ready to ship is something special.

Built with precision, passion, and a whole lot of horsepower, these twin 572s are ready to make a statement wherever they end up.

The only question is... what are these beasts going into?

🔥 383 STROKER. THE SWEET SPOT OF SMALL-BLOCK PERFORMANCE. 🔥

The 383 has earned its reputation the hard way—by making great power, delivering mountains of torque, and putting smiles on drivers' faces for generations. The Smeding Performance 383 Short Block is built for enthusiasts who want a foundation that can take the abuse and keep asking for more.

Whether it's destined for a street machine, muscle car, or weekend track toy, this is the kind of engine that makes every green light look like an opportunity.

More cubes. More torque. More reasons to hammer the throttle.

💥 406 CUBES. ZERO COMPROMISES. 💥

Not every build needs an LS.

The Smeding Performance 406 Short Block delivers the kind of small-block Chevy torque and attitude that never goes out of style. Forged internals, proven durability, and a foundation built to handle serious abuse when it's time to put your foot down.

Because there's still something special about a rowdy SBC that shakes the ground at idle and pulls hard through every gear. 🔥

🏁 Built for power.
🏁 Built for punishment.
🏁 Built by Smeding.

🔥 THE FOUNDATION OF BIG HORSEPOWER STARTS HERE. 🔥

You can bolt on all the power adders you want, but when the boost comes up and the RPM climbs, your rotating assembly has to be ready for the fight. That's where Smeding Performance LS Crankshafts come in.

Built from 4340 forged high-tensile-strength alloy, these crankshafts are shot peened, heat treated, nitrided, and engineered to handle serious abuse. With features like gun-drilled journals, installed reluctor wheels, and ratings up to 1,300+ horsepower, they're designed for builders who aren't interested in doing the job twice.

Whether you're putting together a street bruiser, a boosted LS monster, or a full-on race combination, start with a crankshaft built to take the punishment.

⚡ Strength. Precision. Reliability.
⚡ Built for LS power.
⚡ Built the Smeding way.

The Smeding Performance SBC Power Adder Long Block was designed for one thing: handling serious horsepower.

Built with a heavy-duty 4-bolt main block, forged crank, forged rods, and forged JE pistons, this combination gives you the confidence to crank up the boost, spray the nitrous, or bolt on the blower you've been dreaming about.

Because when the power level goes up, your engine better be ready.

This one is.

🔥 Forged from front to back
🔥 Built for boost, nitrous, and superchargers
🔥 Ready to support your horsepower addiction

The only thing left to decide is how much power is enough.
