Funny, newer gen Cadillacs have factory installed fuel injected LS engines. Maybe you haven't stayed up to date. Thrush glass packs are illegal with our state inspection as well. A little extreme on the comparison. I feel a mild exhaust system will suffice.

An LS engine transplant on an old Cadillac Brougham would cost a ton and be a fairly large project (a good amount of stuff would also need to be replaced too) - to the point of not being worth it. It's much easier in that case to just go out and buy a new model Cadillac instead.
