Just wanted to show every body my project. I will try to show as many pics as possible for those considering the same cummins/chevy swap.

Disclaimer: I don't have all the answers I just give you my ideas for your consideration. Also I am new to posting so bear with me if my post seem awkward or hard to read!!


These pictures are from the beginning.
Truck was a 3/4ton GMC with 350 sbc, 4sd manual tranny and np208 t-case
The Cummins was an ebay purchase from a hail damaged 95 dodge 2wd auto.

I almost did that conversion on my 77 Chevy, but the body was rotting & I felt lazy. I'd still like to see how it fits in there....bet theres lots of room.

Stainless steel header/manifold from Overkill Parts Co.
I just go it friday and have never seen anything like it!
It is a three piece slip joint tube manifold with a T3 flange and pyro bungs.
Definitely lots of R&D plus superb craftsmanship.
Thanks Guys!!

looks good! i have an 84 chev with a 12 valve in the garage just waitin for some more parts. What is the tranny your using out of?
 
The tranny was bought on ebay and I believe it was from a 98 dodge 4x4.
If I remember right it has a 10 spline input and 32 spline output.
 
Looking good! Those square body Chevy/GMC's always did look sharp in a reg cab/long bed/4x4.:rockwoot:
