If you want to maintain originality just get a core block from a volume engine rebuilder and go from there? They are also on Ebay quite regularly, or if you want a small increase use a run of the mill 302 shortblock. Most other parts are interchangeable.
The 302 bore is the same but the rods in a 289 are longer, the same length was used in the Boss 302 to improve rod angle on the 302 stroke (3.0" vs 2.87).
