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.

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
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.

thank you, i will let you know, but i think mine would be rebuildable (atlest get a core charge back)

I would have to agree with 75F350 - loosen of the rockers one cyl at a time and try to turn the engine over by hand. But i think that you'll find a few may be hanging up if the timing gear/chain has failed. Good luck!

Thinking the Government stimulus plan is working is like thinking that taking water form the deep end of a pool and dumping it in the shallow end will raise the water level of the pool.

a 5 gallon bucket:

so we are almost sure it is a conecting rod, we could push it around but the other parts were to big to pull out.

Bummer! Well, a long block is the easiest route anyway. Just not the cheapest.
but if the rod hit much (all those bangs i heard) i will have to replace enough to pay for a $1,800 460 long block...

Yeah, that's what I was trying to say. If you've broken something in the bottom end, I don't think you can rebuild for the cost of a long block. Unless you just replaced one hole, and I don't think you would do that.
I hope you pull it and open the pan. I'm curious as to what all those pieces are. Can't tell much from the photos.

i have to, not sure a long block comes with a pan or not...but i will pull my pan off, there should be a BIG piece in there...

that sucks brady! i think you should forget what everyone else is saying and put a cobra helicopter jet engine in that thing , you already have a rare truck make it one of a kind with a chopper jet engine in it and itll HAUL too, towing might suck youll have to dump the exhaust out the side, not too close to the tires though, wouldnt want to melt them!

I'd say piston pieces. Something heavy is laying in the bottom of the pan.
It will be interesting to see just what all went away. One thing's for sure - the crank is locked up tighter than a bulls ass in fly season. The cam will wiggle a little bit (mucho slop in the chain) but the crank will not budge at all.
