Need a little advice....."new" guy.

[Durney]

Looking for a little help with finding a new project. But first a little background, I own a Competition Engine R&D facility and to be quite honest lost my interest in automotive projects years ago as thats what i do for a living. Anyway I stumbled across a 1968 GMC 3/4 ton 4wd sitting for sale a couple months ago and fell in love with the "look" of the truck. I looked at it once and decided it was too butchered for my tastes and passed. (it has since sold). What I will be doing is a 100pt resto. with a powerplant of my own design that will be used daily. I want it to look bone stock right down to the dog dish caps but be fuel effiicient and obviously make MORE than enough power...(thats the easy part).
It will more than likely use an 385" LS1 (I think theres a spare just off the dyno) or a 362" Bowtie with the 4L80E (from a friend at GM's raceshop).


After looking around the net it seems the 3/4 & 1 ton 4wd stuff is harder to find than I thought & now I find myself even looking at a Chevrolet & diff. years.......

Sooo... What I need to know is was there flaws in certain 3/4 ton 4wd's ( axles,suspension & transfer primarily)?

Are the majority of pts. interchangable?

Wheres the best place to find one?

(I do have a real nice 97 Suburban SLT 4wd in partial trade)

thanks guys and i look forward to any answers - SG
