LT1 HEAD & CAM UPGRADE

LT1 | Head & Cam Upgrade

The HP-F LT1 Head & Cam Performance Package has been developed for enthusiasts seeking the ultimate naturally aspirated upgrade for their LT1-powered vehicle. Combining a premium camshaft package with professionally CNC-ported cylinder heads, this package delivers substantial gains in horsepower, torque and throttle response while maintaining outstanding drivability and reliability.

Every upgrade begins with a comprehensive pre-upgrade dyno assessment, establishing baseline power and torque figures before any modifications are carried out. This provides an accurate benchmark and allows us to clearly demonstrate the gains achieved throughout the upgrade process.

At the heart of the package is a complete BTR camshaft upgrade paired with Higgins CNC-ported cylinder heads featuring upgraded stainless steel exhaust valves. This combination dramatically improves airflow through the engine, allowing the LT1 to breathe more efficiently and produce significantly more power throughout the rev range.

The upgraded cylinder heads maximise airflow on both the intake and exhaust side, while the performance camshaft enhances valve timing and engine efficiency. Together, these proven modifications deliver stronger acceleration, improved throttle response and a more aggressive power curve that transforms the driving experience.

To ensure long-term durability and reliability, the package also includes a BTR trunnion upgrade, providing increased valvetrain strength and confidence under demanding conditions. During installation, all required service components and consumables are replaced, including a new harmonic balancer seal, engine oil filter, premium synthetic engine oil, coolant and associated gaskets and fluids.

To unlock the full 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, airflow modelling and overall engine performance, ensuring safe, reliable and repeatable results.

The package also includes a custom TCU (Transmission Control Unit) calibration, engineered to improve shift quality, increase shift speed and optimise transmission operation to suit the enhanced power and torque 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 completion of the package, you'll receive a detailed dyno report showcasing the final power and torque improvements. The result is an LT1-powered vehicle that delivers exceptional naturally aspirated performance, stronger acceleration, sharper throttle response and a truly exhilarating driving experience, all backed by HP-F's commitment to quality and reliability.

Experience the full potential of your LT1 with HP-F's professionally engineered Head & Cam Package, delivering serious naturally aspirated performance both on the road and on the dyno.
