77 Pickup / 79 Suburban Parts Interchange ?

[LHart]

Hello, boy do I feel lucky to have found this website. Looks like a lot of knowledge is here and I need help.
I have a 77 Chevy full size 1/2 ton that was a real disaster a year ago. Have just finished restoration on frame and body.
It is factory equiped with a 230 cu. in. and automatic that runs great.
Here is the question.---------------
I have a chance to get a 79 1/2 ton Suburban rust bucket with a just rebuilt 454 and a good automatic.
Will the engine and trans swap work into my pickup?
Frame stands? Engine mounts? Crossmember? Radiator? Manifolds? Etc.?

Want to do this but don't want to do it unless it can be done with a factory equiped appearance.

Thanks for any help.
