Yes, you are going to pick up some low end torque with the cam change. Also, going to 114 LSA is going to up vacumm and smooth out the idle some. Gas milage--maybe a little better.
I'm running Dual Quads and the 30 30 cam with 254 effective duration on 114 LSA , this being a solid lifer cam, it is more efficent.
