Well yes it can. But, with a big heavy car like a G-body it will not really shine. To get a true 250 HP out of a 4.1 it has to be fairly well built. So, a nice single plane intake, big cam, etc. Those parts don't really fit into the emissions requirements too well. With closer to stock parts, 200 HP is very doable but that will be a bit underwhelming performance wise. Now put that same engine in a Vega (1000 pounds lighter) and it can be a real performer.
