Thanks for asking, Bob. My ZZ4 motor is out today so the new one is going in over the next few days. While it's out my buddy is rebuilding my TH350 with some beefy parts to handle the torque. I still need to get headers...first I thought about larger block huggers, then thought about having my buddy fab up some custom ones but I really want to keep it inside the frame for now, so I decided to go with Sanderson long tubes like this pic below and we'll make some exhaust pipes and use a couple of Magnaflow mufflers.
