Sorry to hear, but nobody can diagnose what happened over the internet. Just a bunch of random guesses from people. Tear it down and take some pictures of the parts, that would be the best thing to do at this point.

Who built the engine?

Sounds like someone messed up the rod clearances. Time to tear down, hope that the crank is ok, and put in new correctly sized bearings.

Like dude said above, it's no more than a shot in the dark from here. You need to tear it down and take pics. If it is truly rod knock, then it's likely you have an oiling issue, or bad bearing clearances.
