Motor swap?

I've got a 96 camry with a V6 engine that locked up out of the blue. The yards around here all want between $800 to 1200 for a used motor. I just happen to have a 92 with a 4cyl with low miles that's a parts car and was wondering if I can swap them out? I have the transmission and all harnesses as well but not sure what all it would entail or if it's even possible. Any of you wrenches have any experience with this?
