do not start it again...by doing that you are making a bigger bill for your self.

you threw a rod..probley do to cap failure or you could have snapped a crank.more then likely its a rod.

you need a new short block that is only if you did not smash the combustion chambers on the head.

to keep your current engine..
crank will more then likely have to be turned.
new rod or rods.
block will need to bored over not sure on how much untill you tear the engine apart and inspect it.
new pistons will have to be orderd
new pan
rebuild kit
your looking at a grand for sure atleast.

which you could get a complete used engine for that much but your engine will be brand new.
