Re: 72 k20
the cross member for them is different. there is currenty a thread about this, and that the 4X4 x-member is different yet. however, if you're a good welder, you can get around this.

Re: 72 k20
I never bought the truck so I don't know how they did it but in my old neighborhood there was a little old man with a factory 1969 K20, 4-speed. It had a 292 in it with "8-350" badges on the fenders. I asked him about that. He said the 350 was a dog so at around 18,000 miles he brought it back to the dealer and had them install a 292.
The truck had 41,xxx on it when I saw it last in 2002. Long story short it is possible. I would find a donor 71 or 72 that came from the factory with a 292. That way you'd have everything correct which in my experience makes it much easier to get parts when you need them.

Re: 72 k20
The deal with the 292 is it's the only motor with the mounts are staggered. That is what you need to deal with.
