440 wrist pin noise?

I'll but that your noise is the converter. I had the same thing happen to me. It sounded like the rods were cumming out through the pan.
When the trans is in "park" (and it has a stock valve body) there is no fluid going to the converter. That's why the noise seems to go away when you put it in gear.

The noise only comes from the passenger side at the head it sounds like. When I climb under it the sounds not at the converter or the pan it's above my head at the head or exhaust manifold. I had work done on the exhaust manifold and when I took it off it was cracked. I had a guy look at it and swear that's the problem but I can't see how that could make all that noise.
