The 650 cam pictured is a Stage I Hot Cam so that why it looks bigger because it is. Lobe lift on the XX cam is .255/.259 and the lobe lift of the stage I is .307/.307
Smo0oth is gonna have a 11:1 CP, this stage I cam and my XXR ported head so we will see when he dynoes it, he said hes gonna have a stocker dynoed to compare the two on the same dyno.
