I'm pretty sure the Tahoe is too wide in terms of track width. As has been said, measure that and check it out. Even if it fits, it might not be as easy as you think. You'll likely need to reposition the engine in order to get it to fit properly with the '52.
You could always use the 5.3 from the Tahoe along with the wiring harness and ECU and get a different vehicle as donor for the frame.
