lx mike is right, a 408 would put out a lot of torque. That in mind, i dont think the systemax kit would be the best choice. First of all, the cam sucks. Second, the aluminum heads flow pretty well, but I have heard that you can melt them to easily. The systemax upper intake has very big very long runners. Long intake runners tend to build torque, something you will already have an ample supply of. I think you should look for an intake with runners that are a lot shorter than the systemax runners.
Hope this helps.
