'87 350 TBI swap difficulty

[turbo350]

I've got an '87 G20 with the 350 TBI and 700R4. Motor and trans run great and they've been maintained meticulously by the original owner until I bought it from him recently. The body is going to heck with a few spots almost completely rusted through on the body! Anyhow I was looking at how difficult it would be to yank out the motor and trans and put into my currently motorless '78 1/2 ton Bonanza 2wd. I have always dealt with engines that aren't computer controlled and did not have all kinds of scary electronics to worry about. Anyone have a checklist or detailed advice or good reference literature that would help me do this sawp. I was looking at the GM universal crate motors but this '87 350 runs so well I'd like to stay with it.
