Have any of you had experience with a 396 in one of these trucks? As I've mentioned, I am putting in a 3.54 Dana 60 that came out of a 1968 C20 Suburban. Those C20 Suburbans got the 396/TH400/3.54 D60. I was going to install a vortec 350, but I am wanting more torque, and am looking at a 396. My truck will have the Ranger Overdrive, SM420, and Dana 60.
