Loud noise from engine, SUCKS!

Well, it's days like today when I just want to call it quits. Too much stress. Had 1 good fun day at the track but not sure it was worth a couple grand.
New stroker is making a loud rattling noise seems to be more to the passenger side. I thought it might be rockers but got those adjusted and still making the noise. Can the converter do that? if so, how do I narrow down what it is. It doesn't sound good.
