Re: My swap. 5.3 into a 1990 3/4 ton 4x4 Suburban.
I don't think anybody has a good solution for ls 4wd swap headers i think my4by2 had some lucky with i think... trailblazer headers with slight fitment issues he's went through a few headers trying to get the right ones not 100% what though
And its probably easiest to use the tranny that goes with the motor as far as wiring goes but thats my opinion ill be using a 1991 4l80e and swapping out the plug from a new 4l80e so the wiring is the same and my 6.0 is on the way so im watching this thread since its a near mirror image of my build =-p
