BTS3 L67 Camshaft & Valvetrain Package
The Built by Boost & Tune BTS3 L67 cam package is a complete performance camshaft and valvetrain upgrade package for the supercharged Holden L67 3.8L V6.
Designed for strong street performance with a broad usable powerband and a tuff wide sounding idle, the BTS3 profile combines increased duration and valve lift with a 115° lobe separation angle to suit performance L67 combinations where improved airflow, stronger mid-range torque and increased top-end power are required.
Suitable for factory L67-powered vehicles and other vehicles converted to an L67 engine.
