So we got a Magnum 360 with the LA 360 hydraulic roller cam, air gap intake, and shorty headers. If it's got a 3.55 gear with a 31 inch tire and a tight converter, the torque is all kindsa right for this deal. It's going to depend some on how close the tune is to optimum (I get the feeling it's probably dead on), but it will depend more on traction. It's really a solid 16 second deal, and 15s wouldn't surprise me at all. But those hard and open tread all terrain or mud and snow tires on the rear are going to be the real limiting factor here. Going by the burnouts it can do after the cam swap, there is no doubt the power is there for sub 17 second runs.
