Texas Speed & Performance (TSP) 228R Camshaft Specs (25-TSPTsunamiV2): 235/240 .629"/.615" & Your Choice of LSA: 111 OR 112
These camshafts have a 3-bolt timing gear pattern.
Texas Speed and Performance's cams are known for consistent power production and are a classic selection for any GM LS1/LS2/LS6 and even 5.3L/6.0L combinations.
From Texas Speed:
"The Tsunami camshaft features aggressive lobes that requires a good double valve spring kit. For customers looking for a quality double valve spring kit, we recommend the PRC .650" & .675" double spring kits. Both spring packages will easily handle this camshaft. The new more aggressive intake lobes & small changes to the camshaft design has allowed us to create more peak power while bringing power in early in the rpm band. With the Tsunami camshaft we typically recommend the customer have at least a 3500 rpm stall converter for automatic cars. Tuning will also be required in both automatic & manual applications.
The Tsunami camshaft is a large max effort camshaft that has slightly more p/v clearance than the Magic Stick line of camshafts."
