Noise between bellhousing and Engine

What did you find?
well... absolutely nothing. All bolts were tight. No rubbing between anything. Even swapped out all the rod bearings (old ones were fine, one was scratched, had about 1000 miles on em). Cylinder walls looked clean, wrist pins moved freely. I've just been driving the truck. Beating on the engine. Few longer trips. Runs like a champ as of right now. So... I'm just driving it until something happens. And if it does... maybe time to build a stroker... bit the noise may also be trans idk
