v-6 in early A-body

Hi guys, I'm sorry that this post started so much trouble. I merely wanted to know if this combination could work, and as far as I can tell, it will. What I am wondering though, is how expensive would a job like this be?
I know I could find a small block (318, 273, 340, 360) somewhere if I looked hard enough in my area, but I still think that the V-6 would make a really cool ride. I am just not sure about the whole fuel injection part of the job. I think that I would have to find a carb version to work with.
