This camshaft kit delivers high performance for the street or the track. The profile of the popular Sifton 460 sport cam is used for the intake while the race profile of the MAP1052 is used for the exhaust. This cam set offers great mid-range power with increased delivery as well. It's not too radical for the street, but delivers enough power for the weekend racer.
