BTR PDS STAGE IV CAMSHAFT

Some more info about the BTR PDS STAGE IV CAMSHAFT

The most aggressive camshaft Brian Tooley Racing offers for GM LSA & LS9 engines. It features an authentic and aggressive idle. This cam is recommended when looking for more power than our Stage III application offers. It is perfect for use in high RPM applications, or if using aftermarket or ported cylinder heads with overdriven superchargers. This cam uses ultra stable lobes for higher RPM potential, and has proven to be extremely durable in testing.

Cam specs are 235/252 .629"/.600" 119+5, and comes with a 3 bolt timing gear pattern.
