The cam is a Comp hydraulic roller with 242/248 duration at 0.050 and 0.584/0.579 lift using a 1.6:1 rocker. The LSA is 113 degrees. The theory is that a cam with a lot of duration and overlap will create a lot of reversion, and the cam selected should be based on the rpm range of the engine. A huge cam that doesn't peak until 7,000 rpm, is going to be a pig everywhere else in the powerband.
