Texas Speed Stage 2 Cathedral Camshaft

TSP Cathedral Heads Stage 2 Cam Specs: 228/232 .600/.600 112 LSA

The Stage 2 camshafts use lobes that are designed to be both beehive & double valve spring friendly. The Stage 2 camshaft is a very popular camshaft for customers wanting a very streetable camshaft that makes approximately 5-7 more horsepower than the 228R camshaft. Dyno testing has shown the Stage 2 camshaft to make a solid 50-55 RWHP gains with all other supporting bolt-on modifications in place. The Stage 2 camshaft is large enough that we recommend a minimum 3200 RPM stall converter in automatic cars.  Tuning will also be required in both automatic & manual applications.
