Hmmm. That's a lot of miles. Will you be changing the trans too? If the trans has the same miles and is staying, I vote get another car. Maybe you can find another Bonneville pretty cheap that might need some parts that can be pulled from the dying one.

With the right tools and skills, a motor swap isn't really too bad. Perhaps a full weekend for a shadetree mechanic if everything cooperates. Used motors around here are around $400. $1K sounds more like a remanfacturered one.
