genIII help

Hi I'm a new member. Just wanted to ad a little info. I have always been a diehard MOPAR Man. I have a 1970 RT/SE 440 Challenger, had it since 1978 when I was 14. Also a 2005 Magnum RT with a hemi. thought they were great motors until this weekend. It started making engine noise on start up. pulled plugs and looked in the cyl. with my bore a scope and I'm I can see past my top ring and can even see the wrist pin. bought it brand new, still all stock, had the oil changed on time every time. 73400 miles and it not even a good core! I believe it lost a seat first with in less than a minute of run time since first noise ( up the driveway into the garage) and it is a boat anchor. will post pictures later. Just had to vent, hope it helps someone else.
