newer engine to 72 nova swap

i have a 1990 silverado 5.7 350 that runs great(was rebuilt recently) and i want to put it into my 72 nova(which has a straight 6). From what i have found searching, is that i will need new motor mounts, springs, radiator, and i have a muncie m20 to go with it. My question is, the engine is TBI so how does all the computer junk come into play? Also what will i need to hook up the m20? Im looking for the easiest way to get this done. Thanks for reading!

I'd personally go over to the Team Nova site and ask there. I'm sure someone has the same set up (maybe) and can give you the straight scoop. Their forum is quite good and user friendly.

Furnace, with gas prices going up every hour are you sure you want to yank out the 6-cylinder?
Your car probably is numbers-matching now. Dropping in a 350 that isn't period-correct will hurt it's value. (I assume you have a 2 door coupe and the engine still runs)
Don't get me wrong - I love V-8's and I've had a TBI Chevy truck engine and liked it.
But there may be some regrets down the road if you pull that engine. The 6's are easy to work on, easy to get good low-priced parts, and can be built up to look pretty and sound good too. Maybe an Offenhauser intake, split dual exhaust, finned valve cover and side plates and some other pretty stuff.
Just a suggestion - this is less complicated than trying to modernize your car with a truck engine.
