GenIII engine swap into 70s 4x4 truck???????
 

Has anyone swapped a modern engine 2000 or newer 5.3L or 6.0L and 4L60e or 4L80e transmission into a 70s 4x4 truck?
I am looking for any parts ideas or tech links I can find before I start.
Things like custom engine and trans mounts would be a big help. Drive shafts would help as well.

Any Ideas on what transfer case to use?

Thank you
Otis
