Junkyard treasure 360 efi?

I see, my end idea of the build is to tap fuel injectors into my chosing of manifold maiting to heads of my liking. This Idea is a small budget efi conversion. The Junkyard 5.9 could have internal issues, my 360 is good in and out. With the knowledge you have given me, would i be able to install efi in say... my brothers 383 by rewiring injector connections to his firing order?

Thanks for the Feed back.
