engine locked up
i have a mid 80s 460 in front of a C6 in my 1970 F350, So i was driving down the freeway (constent speed of 60) when all of a suden it started to make a pownding noise, almost sounded like a belt split and was thumping on something. so i pull over and it made the noise untell i turned it off (i almost thought it might be a flat tire that split). so i get out and cant see anything worng with the truck. so i get it towed home so i can work on it. well i go out and check everything i can see, the dizy cant move and when i canked it (twice, without the dizy cap on) the rotor turned and everything else turned too (alt, power steering, water pump). no pullys were loose. so then i decide to see it will start and see if i can hear it and find the noise. well the starter will engage the fly wheel but will not trun the motor over. so i put a breaker bar on the crank and i could not get it to move at all. and i really tried to get it to. so now my question to all of you, what do you think it could be or how could i fine out without having to really pulling the engine apart?
any help will be great.

i did pull them all and nothing really looked all that off, i can take pictures of them but not sure if it would help or even if it would come out right.
i also pulled the starter and the flex plate doesnt look bad.
in the AM i will drain the oil.

the water temp was fine, oil pressure was fine (as good as the stock gauge works), dont know the oil temp. but it didnt look/sound/smell like it was over heating when i opened the hood on the side of the freeway.

You did all that wiring, and didn't put good gauges in? tsk-tsk. lol. Like has already been said pull the valve covers and then the pan. You will probably have to raise the motor to get the pan off. good luck

ok all oil drained and both valve covers off. here is what i found:
this is the biggest thing in my oil...there was not much of it. (the blue is a glove and the little brow item felt like grim or dirt or metel shavings
i couldnt find anything wrong or that looked different then the rest of anything. to see all the different pictures go here: Ford Trucks pictures by bradycouchman - Photobucket

As the process continues you will end up taking the timing chain cover off to see if the chain broke. You have have a busted gear or chain and a piston is up against a valve.
You could loosten all of the rockers to see if they will free up a piston. Once all of them are loose are removed, it should isolate the valve train from the equation.
If the engine turns after that, you can then remove the timing chain cover to reveal what went wrong.
