Just a little update finally ordered my headers, tune, and my yoke for the tranny swap will be happening real soon. Ill be starting the swap as soon as everything gets here.
Have a couple questions is the 454 radiator a different size than the 350 one? Im moving to cali in april I am towing the yukon with my truck. What should I do to prepare for this suspension wise? Would I be fine with just a helper springs for towing or should I get 2500HD springs?
