I'm guessing base circle lift, It is listed on Cranes web site as a .619 lift along with the durations and it also states that this cam selection requires performance intake and exhaust systems. Based on the dyno run the torque and horsepower is not coming on until the engine is above 3500 rpm's and that's the point I'm trying to make with the builder. I shared my configuation with them along with my riding style which never see's the RPM needle rise above 3200 RPM. Since he claims no foul I dodn't know where to go from here. Idea's....
