Unhappy 2000 Mustang 3.8L V6 clanging then sieze?

I have a 2000 Mustang 3.8L V6 with 145K miles. All seemed well until earlier today while driving normally it made a loud clanging, metalic sound and then quit. It only makes a loud click and does not turn over when trying to start. Sounds like the starter is engaging but cannot turn it over, yikes. I got the vehicle out of the way and am having it towed to my home so I can start investigating. Has anyone had this happen to them or Does anyone have any ideas what I am in for? Just guessing, possibly head gasket and one or more cylinders has coolant in it and can't compress?? Is there anything that can "jam" causing these symptoms. A mechanic friend said it sounds like it siezed and need a new engine..? Please, help.

Sounds like a thrown rod and major engine damage to me, but you really need to properly diagnose it. Internet diagnosis is tough even with more info.

Take a 21mm socket and put it on the harmonic balancer to see if you can get the motor to spin by hand. It sounds like you threw a rod. Sorry.......

Car is being towed over here now. I'll try manually turning over with the 21mm on the HB. Sort of expecting the worst with the clanging noise (possible rod). Whats the least expensive fix?

Does anyone know of a reliable place to get a good used or rebuilt 3.8L for this 2000 Mustang in Michigan? Have any idea what they cost? What is the car worth on the market?

Got it here and it didn't take long to find the 4x5 chunk of oil pan that was blasted out by the snapped rod...yikes. Found a new crash engine with less than 1K mi on it. Getting it delivered Monday to begin the R & R process...Does anyone have any suggestions on what to look out for during removal or replacement. Never done a 3.8 before.

you're just pulling the old engine and plopping the new one in there? what year did the other 3.8 come from? you have to make sure you have the engine balance in consideration and that you have a weighted flywheel/flexplate for the externally balanced earlier 3.8's and a neutral for the internally balanced ones.. other than that, just keep track of your sensors, wires and vacuum lines and you should be fine
