LT1 CAM UPGRADE

LT1 | Cam Upgrade

The HP-F LT1 Camshaft Performance Package has been developed for enthusiasts looking to unlock the true potential of the GM LT1 engine. Combining a premium BTR camshaft package with supporting valvetrain upgrades and custom calibration, this package delivers substantial increases in horsepower, torque, throttle response and driving excitement while maintaining excellent reliability and drivability.

Every upgrade begins with a comprehensive pre-upgrade dyno assessment, establishing baseline power and torque figures before any modifications are carried out. This provides a benchmark against which the final results can be accurately measured.

At the heart of the package is a complete BTR camshaft upgrade, designed to improve engine airflow and optimise performance throughout the rev range. To ensure long-term reliability and durability, the package also includes a BTR trunnion upgrade, supporting the factory rocker assemblies and providing increased confidence under demanding conditions.

During installation, all required service items and associated components are replaced, including a new harmonic balancer seal, fresh engine oil filter, premium synthetic engine oil, coolant and related consumables. This ensures the engine is returned to service in optimal condition following the upgrade.

To maximise the performance potential of the hardware upgrades, HP-F performs a complete custom ECU calibration using HP Tuners software. Extensive dyno testing is utilised to optimise fuel delivery, ignition timing, throttle response and camshaft operation, ensuring the engine delivers safe, reliable and repeatable performance gains.

The package also includes a custom TCU (Transmission Control Unit) calibration, designed to improve shift quality, increase shift speed and optimise transmission behaviour to suit the enhanced power output of the upgraded engine.

Once tuning is complete, every vehicle undergoes comprehensive dyno and road testing to verify performance, drivability and reliability. A final dyno run is then completed to compare against the original baseline figures, clearly demonstrating the gains achieved through the upgrade.

At the conclusion of the upgrade, you'll receive a detailed dyno report showcasing the power and torque improvements achieved. The result is an LT1-powered vehicle that delivers stronger acceleration, sharper throttle response, an aggressive performance sound and a significantly more engaging driving experience while retaining the reliability expected from a professionally engineered HP-F upgrade.

Experience the full potential of your LT1 with HP-F's dyno-tested Camshaft Performance Package, engineered to deliver impressive real-world performance both on the road and on the dyno.
