Brian Tooley Racing (BTR) LS1 / LS2 / LS6 Cathedral Port Camshafts
Brian Tooley Racing’s cathedral-port camshafts are built to wake up LS1, LS2, and LS6 engines with the perfect mix of power, sound, and reliability. Each grind is engineered to take advantage of the airflow characteristics of early LS cathedral heads, delivering strong mid-range torque and crisp throttle response. Whether you’re after a street-friendly chop, a weekend strip setup, or a boosted build, BTR’s cams give you proven results and that unmistakable BTR idle. When you want your LS to pull hard and sound right doing it, these are the cams that get it done.
