Toyota 83 2wd pickup engine swap

I have an 83 2wd pickup with a tired 22R engine that has always been a bit underpowered for towing. I have heard it's theoretically possible to swap any toyota rear wheel drive engine into another rear wheel drive car; anyone actually swapped a six into a 2wd pickup?
Thanks for any info

you need to place this thread in the Toyota section, this is Chevrolet!
