Welcome to Lat-G
I guess you can always start with the basic lowering, wheel, tires, exhaust to get the look going on the Monte. I assume some common parts here might be hard to get there so you might have to get creative.
I don't know much about the new SS, but I think they are supercharged. I read somewhere they have been planning on coming out with a 5.3 V8 soon as well.
Military? My bro-in-law was over there for a while. He enjoyed it. He bought a BMW while he was there to cruise around.
