408 4x4 build

I think your heading in the right direction with this build 4X4, but i would change a few things just a little. The cam is a bit on the big side for what your after. So dial it back a bit. Hughes cams are ok, but I have made more torque with the Voodoo cams over any other of the same size(apples to apples). They just wrok. A 60403 will get you a ton of torque and still make good power, have a good idle. But if Hughes will do a swap for you(no extra $), I would go with their 2832 cam.

On the bottom end, Stay away from the Eagle I beam rods, spend a few $ more and go with the SCAT 4340 I beam rods. Much better rod, and lighter/stronger than the 5140 Eagle rods.

The RHS heads are going to be just right, and I would run the 1.92 intake valve. You dont gain much from the 2.02 unless you port the heads and the 1.92 is less shrouded. For the $ spent to go to a 2.02, you wont see any real gain. Put that money in the rods.
