Brian Tooley BTR Turbo Stage 4 Camshaft V2 Fits 1997-2013 LS Based V8 Engines 4.8L 5.3L 5.7L 6.0L 6.2L Specs: 227/24x .618"/.618" 115LSA, 3-Bolt Pattern Often Imitated - NEVER duplicated! The Stage 4 Turbo cam has earned a reputation in hundreds of stock stroke applications. Paired to an S400 frame (or similar size), this camshaft will help you move some serious air past 7500rpm on stock displacement engines. Regarded as the BIG STICK of our turbo cam lineup, the Stage 4 is here to knock it out of the park. If you have a ~408" bottom end spinning it in the 6400-6800rpm range, this is also a very good fit. This is the go-to camshaft for 1,000+hp turbo stock block combinations.
