I am very interested in this swap. I like how simple and tidy everything looks. I am thinking about buying a 1 ton crew cab short box and installing a 5.3 in front of a 4l80/205 setup. I understand it only requires a spacer behind the flex plate to bolt up the 5.3.

The MEI4 setup is certainly simplified and wired up nice and clean for sure. To comment on the 5.3 hooking up to a 4l80E, you don't need any goofy overpriced swap flexplate from Advanced Adapters or anything like that. The 5.3 was never mated with a 4L80e from the factory, but lots of 6.0's were. All you need to do is order the flexplate, spacer and bolts for a 3/4 ton equipped with a 6.0L and the 4L80e. 2002-2007 ought to cover you for the year range. Getting the plate specific for the 4L80e will have it bolt right up instead of the "adjustment's" we had to do to mate the 4L60e's flexplate to the 700r4's converter. Keep in mind all LS truck engines are internally balanced so the flexplate is interchangeable from the 4.8 to 5.3 and 6.0 designs.
