not A body; but need big block truck help!!

I'm putting a 400 from a tradesman van into a 1977 dodge 1/2 ton, seemed easy at first, then the mounts didn't want to line up; when they did the engine sat crooked and the manifolds don't seem to want to fit

can anyone with a 1972-1980 big block truck post a few detailed pictures of the mounts and manifolds so I know what I need to go or buy mines 2wd I think 4wd mounts are different

any help appreciated
