Omni LT4 Street/Race Package (Stage 3)

The Omni LT4 Street/Race Package is where the LT4 platform truly comes alive. Designed for Corvette Z06, Camaro ZL1, and Cadillac CTS-V owners who are ready to move beyond traditional bolt-on modifications, this package transforms your LT4 into a serious street and track performer.

At the heart of the Street/Race Package is the Omni Cam Package—our complete camshaft system built around a custom Cam Motion camshaft and the supporting components required to do the job right. From the aggressive idle to the broad powerband and impressive horsepower gains, the Omni Cam Package delivers the performance enthusiasts expect without sacrificing reliability.

Unlike many camshaft installations that reuse critical components, the Omni Cam Package includes the supporting valvetrain, DOD/AFM delete components, upgraded hardware, premium engine components, and fueling upgrades needed to ensure long-term durability. Every vehicle is professionally assembled, custom calibrated on our in-house chassis dyno, and built with the same attention to detail that has become the standard at Omni Motorsports.

Automatic Transmission Requirements

To ensure proper performance, drivability, and reliability, automatic transmission vehicles require a Circle D Specialties billet triple-disc torque converter. This converter has proven to provide excellent street manners while delivering the holding capacity required for high-horsepower LT4 applications.

Because the converter changes the operating characteristics of the transmission, every automatic-equipped vehicle also receives a custom transmission calibration to optimize shift quality, converter lockup, shift scheduling, and overall drivability.

Additional Cost for Automatic Vehicles

• Circle D Billet Triple-Disc Torque Converter: $1,575
• Custom Transmission Calibration: $200

Total Additional Cost: $1,775

Manual transmission vehicles do not require these additional upgrades.
