360 magnum. 1 piston lower in cylinder??

So I have my used 2001 Ram 70k Magnum completely disassembled. Still cannot find cause of #8 bent rod. Thinking hydrolock but no signs. Heads good, head gasket good, cylinder walls good with cross hatching. Piston skirts good, rod and crank bearings ok.
I acquired a piston/rod assembly and indexed the crank. Measured crudely with feeler gauge at TDC. All look to be around .050 in hole. My local machine shops are booked for weeks. My next step is to ball home and install new bearings and H116CP std pistons and rings but feeling uneasy not knowing root cause. I did find a thread where it was stated that a bad injector could cause and that engine still ran fine like mine did according to previous owner. This is my first magnum build. Is cracked cylinder wall common? Crank sound good to go? Anybody with experience care to comment?
