TSP Stage 3 Cathedral Camshaft - Torquer v4

TSP Cathedral Heads Stage 3 Cam Specs: 231/234 .629"/.615" 111 LSA

The Stage 3 (Torquer v4) camshaft features a more aggressive intake lobe that requires a good double valve spring kit. For customers looking for a quality double valve spring kit, we recommend the PAC .660" double spring kits. The new more aggressive intake lobes & small changes to the camshaft design has allowed us to create more peak power while bringing power in earlier than the Torquer V2. With the Stage 3 camshaft we typically recommend the customer have at least a 3200-rpm stall converter for automatic cars.  Tuning will also be required in both automatic & manual applications.
