I don't believe it was wider, looked pretty close to the same width. I never measured or anything. It all depends on how you do it. If you put the engine in your 70 frame, you will have to build your own motor mounts and possibly a crossmember. Also to keep it a 4x4 you will HAVE to use a 78-79 ford dana 44 or 60 (60 Recommended) to clear that offset oil pan. My crossmember as you can see is over kill. It can probably be done with 3-4 inches of lift, but there are a lot of factors that can change that. The pumpkin is large, so, how high you set the engine in the frame, how large of a crossmember is used will all determine. You will also probably have to trim the frame rails for the manifolds. The manifolds sit really low on a duramax. Or you could possibly body swap it? Hope that helps
