for info here

transplanting a '98 5.7 vortec from a chevy 1/2ton 4x4 into a cj7 frame. the donor vehicle is running and driving so i am pondering on pulling motor,tranny, and X-fer all together. of course i will use the comp and all from the truck...... truck has 350/5spd/floor shift x-fer case

question:
has anyone ever used a tranny/X-fer case combo out of a truck like this? I know you would have to use a ford 60 up front
have never seen one to my knowledge in a crawler :dunno:

that is my first option, second option is to bolt up the 5.7 to a older th350 or sm465 w/ a 205 and run a chevy 60 front

opinions? suggestions? Thanks in advance

The half ton AL 5spd is not very strong, and from what I've read, is disposable if anything goes wrong with it. I would get an auto. Anything that will bolt to a chevy SB/BB will bolt up to it, so you have alot of choices.

I got the 5.7 LT1 bolted to a TH400 and Dana 300 . I have yet to regret a TH400. They take much abuse and if built properly I think it is the best way to go.

I have a 5.7 with turbo 350 trans and 3.0 atlas - I like it - however the one thing I will change is the trans ever gives up is to install a reverse valve body
