Omni LT1 Max Effort Package (Stage 4)

The Omni LT1 Max Effort Package represents the highest level of naturally aspirated LT1 performance offered by Omni Motorsports. Built upon every previous stage, this package combines improved cylinder head airflow, increased intake efficiency, and drivetrain upgrades to unlock the maximum potential of the Gen V LT1 platform.

At the heart of the package are professionally ported cylinder heads, the MSD Atomic AirForce intake manifold, and a Nick Williams 103 mm throttle body. Together, these components dramatically improve airflow throughout the entire RPM range, allowing the custom camshaft to reach its full potential.

To ensure the power is transferred efficiently to the ground, automatic-equipped vehicles receive a Circle D billet triple-disc torque converter, providing improved launch characteristics, exceptional drivability, and proven reliability for high-performance street and strip applications.

Every vehicle receives a complete custom calibration on our in-house chassis dyno, optimizing the engine and transmission to work together as one complete performance package.
