From previous threads and some experience, the main reason the 289 blocks are not good stroker candidates is the short skirt issue. Really has nothing to do with block strength. The 302 however has longer skirts and stroking is not a big issue.
The old 289 block is super strong, especially if you use the heavy main caps and they do like to rev if you have the top end set up right.
Just my 2 cents
