If you have thrown a rod, chances are it is not expedient to re-ring the motor. Throwing a rod is akin to chucking a large piece of granite into the moving mass of the crank, rods, pistons, etc. It destroys everything it touches, often punching a hole (or several) in the engine block itself making it impossible to salvage. I think the worst i've seen that can undergo a rebuild and still be ok, is a spun bearing or a rod knock that was caught early enough not to elongate the rod by too much. By what you've said, it sounds like could possibly need a reman'ed engine.
If your motor, for example, stopped simply because the bearings melted, (due to inadequate oil) the engine would be rebuildable, however you would most likely need to replace every moving part on the short block (and possibly a few things on the heads as well) have the block hot tanked, checked, double checked and line bored. Then you could be sure it would be last for another 150,000 miles.
I hope this doesn't discourage you. Rebuilding a motor, you being a mechanic will know, is a time consuming, expensive job which i'm sure you will not want to do only ten miles down the road after you've done it the first time. I hope this helps.
