I just re-ringed my 3GM30F. It was neither difficult nor expensive. Runs like a top now. Also wound up hydro-locking once a few years ago but did not bend a rod. It's a common situation with these below exhaust installations. Unless you cannot get up to hull speed, there's really no reason to increase horsepower--just a waste of fuel. I think my re-ring, without a rod, cost around $400 for a new ring set and gaskets, considerably cheaper than a new motor. Did all the work myself and was able to drop the pan right in the boat so did not even have to disconnect the shaft.
Why would you need a new block? If a rod is bent, it does not necessarily do any damage to the block or liner. You should look-see before you spend $ on a block. You know the old saying, "If it ain't broke, don't fix it."?
Marion? You're not at Richie's (AJ) are you? He knows his stuff.
