REAL TRUCKS. COMPLETE COMBINATIONS.
Not just glamour shots. Every featured build is about the combination—engine, transmission, converter, gearing, tire, tune, power and what the owner would change next time.
FEATURED OWNER BUILDShowing all build combinations. Search by engine, transmission, use, chassis, or power adder.
FEATURED BUILDS
Complete combinations with enough context to understand why the parts work together—not just a shopping list.
2009 SILVERADO • OWNER BUILDA real LS Truck Labs build: crew-cab 2WD GMT900 with an LY6, Michigan Motorsports Lumberjack High Lift cam, 243 heads, long-tubes, 4.10 gearing and 275/60R20 tires.
A simple boosted combination focused on repeatability, fuel system headroom and keeping the transmission alive.
A lighter classic chassis built around compression, cylinder head airflow and a converter that lets the engine live in its powerband.
Factory-looking exterior, modern LS electronics and a conservative boosted calibration for a truck that still sees real street miles.
A street-first swap emphasizing cold starts, drivability, quiet highway rpm and OEM-like manners over peak dyno numbers.
A no-frills combination where tire, suspension, launch strategy and repeatability matter just as much as peak horsepower.
BUILD PLANNING
Use factory specifications as anchors, then choose converter, gearing, fuel, cooling and calibration around the truck’s actual job.
Chevrolet Performance lists its SuperMatic 6L80-E at 4.02 / 2.36 / 1.53 / 1.15 / 0.85 / 0.67 with a published 650 lb-ft torque limit. That rating applies to the SuperMatic product—not every production 6L80.
Chevrolet explicitly states its LS SuperMatic 6L80 controller package is for Chevrolet Performance LS-style crate engines and controls, and is not a drop-in production-vehicle service replacement. Mechanical fit does not guarantee electronic compatibility.
A heavy daily-driver, tow truck, street/strip truck and track-only RCSB should not get the same converter, gear, cam or thermal strategy. Start with weight, tire, use and cruise rpm before buying the loudest parts.
FACTORY ANCHORS
These references prevent common “it bolts up, so it must work” mistakes.
| System | Published reference | Build implication |
|---|---|---|
| SuperMatic 6L80-E | 4.027 first / 0.667 sixth; 650 lb-ft published limit | Excellent ratio spread, but do not transfer the SuperMatic rating blindly to a used production unit. |
| LS SuperMatic 6L80 controls | Specified for Chevrolet Performance LS crate-engine control systems | Plan ECM/TCM architecture before purchasing a transmission/controller package. |
| L96 control-system fuel pressure | Chevrolet specifies constant 400 kPa / 60 psi for its crate control system | Fuel-system requirements are calibration/system-specific; verify your exact controller and injector data. |
| Vehicle speed input | Chevrolet crate-control documentation specifies expected pulse inputs for supported packages | Speed signal affects more than the speedometer; controller strategy may depend on it. |
LS Truck Labs rule: factory crate-package specifications are labeled as such. They are useful reference points, but they are not automatically specifications for every production engine, transmission or swapped controller.
Texas Speed's current L92 truck-cam guide lists a 216/228 .600/.600 113 LSA Stage 1 as factory-converter compatible with a published 55+ hp gain, then moves to 220/232 with 2800+ stall and 224/236 with 3200+ stall as the combination gets more aggressive. That is the kind of supporting-hardware context every future member build should include.

The goal is to feature useful builds, not only expensive ones. A clean 5.3 swap with great drivability can teach somebody just as much as a four-digit-horsepower race truck.
