With all that going on under the hood, I would definately move the battery to the rear. Generally the reason for moving the battery is either you are out of room in the front, or you need weight shifted in a vehicle. Typically when you move the battery to the trunk you want it on the torque side of the vehicle. For my car that was on the passenger side in the trunk. For me I shifted about 50plus lbs, from the front to the rear. That helped to plant the rear tires, by not only putting weight bias over top of them, but also allowing the front end to come up better, due to less weight being there. Also be careful with welding cables, as battery cables. If you use the welding cables get the ones with fine copper strands, the cables with really stiff thick strands, has alot more current drop across them, and you want all the current getting to the starter as possible. And Hal is correct, you want the ground the same size as the starter cable.
