back in aug.08 i finished a 520 with EZ-295's on it for a guy. fast forward a year or so, the car comes back to me. he thinks it blew a head gasket. of course, one of the first things i do is ck the radiator.... still full to the cap! i bump the starter...ummmph. it's locked up. so, i start taking the plugs out and i find each one is rusted. then i get to #5 and when i pull it out water pours on the floor. hydrolocked . the guy left the car outside uncovered and somehow water ran into the carb and got into the cyls. needless to say he left the water in the engine too long and rusted up the cylinder walls. talking about a bonehead.........

A few locals over here, father and son, (not mopar guys) both never drained the water from their cars. Both Popped the freeze plugs, who knows what other damage was done. Stupid Bonehead moves, like you said.
