So I am putting a 440 in my challenger since the 318 is blown. I need to upgrade the suspension. I am going with the stock rear bog block springs, but for the front, Im not sure whether 1.0" torsion bar is ok, or whether I would need larger, like a 1.06" or 1.08". I am also putting on aftermarket front and rear sway bars.
It will just be a driver but I would like it to handle better than my CJ7 (although not as rough a ride).
