Lift 440 fully dressed +trans with this?

No, the frame is a combination of 4" schedule 80 steel pipe and a ridiculously hefty 4x8" box cross-member, all welded together and to the body like a unibody type.

Look at post 27, maybe hit ctrl + and enlargen your layout a bit, its a friggn beast of a frame, so narrow that notches are cut so the trans pan fits into it.

It has to be as solid as a 2wd f150 frame in the front half.
