I owned Plymouths almost exclusively from '35 thru '55 (plus a '47 Dodge), all flathead 6's. Serviced them religiously, but never could keeps rods in 'em beyond about 50K miles. The big end of the rod (around the crank journal), would 'stretch' over time, increasing the clearance. All the rods would rattle like heck when you let off the gas going over the crest of a hill at 50 mph. It wasn't a knock either, just that signature "rattle" of every Chrysler product 6 i ever owned.
