Late-Model Specialists

Expert Custom Built LS, LT & Ford Coyote Engines in Wisconsin

When it comes to late-model General Motors (GM), Chevrolet, Pontiac, GMC, and Ford vehicles, the heart of your performance lies under the hood. At Wisco Speed & Performance, we specialize in high-performance built LS engines alongside advanced Gen V LT platforms and robust Ford Coyote 5.0 builds. Whether you are planning a comprehensive LS build for the track, need a durable built 6.0 LS for your GMC truck, want to push the limits of a direct-injected LT1, or are dropping a high-revving Coyote crate package into a restomod, our team has the expertise to deliver.


A proper engine build requires precision, and our modern shop in Rosendale, WI, is fully equipped to assemble the finest custom powerplants in the Midwest. If you desire the classic torque of a built LS motor, the massive displacement of a built LS7, the direct-injected efficiency of a built LT engine, or the quad-cam capability of a fully forged Coyote 5.0, our custom engine assembly services guarantee top-tier, reliable results.

Engine Packages

Unlocking Horsepower: Built LS, LT & 5.0 Coyote Packages

Choosing the right platform is critical for your next build. For performance enthusiasts in Central Wisconsin and Central WI, we offer tailored engine packages specifically for late-model GM, Chevy, and Ford vehicles. Looking to upgrade your Pontiac GTO or Chevy Camaro? A built LS motor remains a legendary and capable choice. If you want massive, naturally aspirated power for a Corvette, our meticulously crafted LS7 packages are unmatched in the Midwest. For modern GM owners, our Gen V LT builds—spanning from the 5.3L L83 to the supercharged LT4—maximize the massive potential of GM's direct-injection technology.


For the Ford camp, our 5.0 Coyote builds bring modern muscle to the next level. Whether you are aiming for a high-compression naturally aspirated track screamer or a sleeved, supercharger-ready block built to handle severe boost, our Coyote engine assembly brings relentless horsepower to modern chassis and classic Ford swaps alike.


For truck and SUV owners spanning from Green Lake, WI to Fond Du Lac, WI, a rugged built 6.0 LS, a modern L86 LT truck engine, or a torque-heavy F-150 Coyote variant provides the ultimate towing and off-road capability. No matter your choice, every built LS motor, robust 6.0 LS, versatile LS3, advanced LT block, or fortified 5.0 Coyote is blueprinted to absolute perfection. From our shop, we proudly provide these exceptional engines to clients from Oshkosh, WI to Miami, Florida.

Engine Swaps

Engine Swaps Done Right

An engine swap done properly is more than dropping a motor between the frame rails — it's mounts, wiring, fuel system, cooling, drivetrain, and a tune that ties it all together. Wisco Speed & Performance handles complete LS swaps and other GM performance swaps from start to finish: the parts, the fabrication, the plumbing and wiring, and the final dyno verification, all under one roof in Rosendale.

How It Works

Spec It. Build It. Prove It.

No two builds are identical, so we don't publish one-size-fits-all engine pricing. Here's how every build moves through the shop — and why you always know where yours stands.

Step 1

Spec the Combination

We talk through the vehicle, the power goal, and how it'll be driven — then quote parts, labor, and timeline straight. No upsell script, no surprise line items.

  • Honest read on what the goal actually requires
  • Supporting mods — fuel, drivetrain — scoped up front
  • Straight quote on parts, labor & timeline

Step 2

Build It In-House

Parts sold, engine assembled, power adders installed, and everything plumbed and wired in the same building — one set of hands accountable for the whole job.

  • Parts sales + assembly + install under one roof
  • Turbo, supercharger & EFI work done here
  • Transmission & differential work handled in-house

Step 3

Prove It on the Dyno

The dyno is in the building, not across the state. Every build gets tuned, verified, and adjusted on our rollers — and you leave with a graph, not a guess.

  • Tuned and verified before delivery
  • 1,000+ HP customer pulls recorded here
  • See Dyno Tuning for the details
