Need some advice help

[Thealien]

I have a nice 1972 GMC Jimmy but am less than thrilled with the drive train. I would like to swap a newer drive line in for the FI and overdrive. The transfer case does throw a wrench in the works. I have 2 brand new drive shafts and the NP205 is bulletproof.

I believe the easiest is a TBI/700/241 With that swap can the TC shifter stay in the same location?

Speedo cable?

Any other problems I should be aware of?

The next consideration is a Vortec/4160/243

One of the problems is the drivers side drop TC

What can I do to accommodate the TC drop?

I like the electric pushbutton 243 so I could just plug the TC hole in the hump?

I am also open to the 5.3/6.0 swaps but know less about them.

If I can't find the correct combination I am going to go 2WD (maybe) with just an engine transmission swap.

I would really appreciate all help, suggestions, and if any of you know any deals out there!! I want to do this over the winter so it is drivable for next spring/summer.

Thanks in advance I know you guys have all the answers!!
