C6 tranny with that granny low……..As an outsider looking in, what I've always wanted to find is a Jeep with no engine. Do a frame-off, and Un-Fuck whatever AMC or Chrysler did. Then install a Ford 300 I-6. And of course a manual transmission.
As one YouTube engine builder said "after the nuclear apocalypse there will be cockraoches and Ford 300's remaining."
