Need a New Motor!!!!!
All you need is a new shortblock.
You can find one for 700-1000 dollars easily in the for sale section.
You will then need a gasket set for all the cover's, heads, oil pan, etc.
That will be around 400-500 dollars for everything including new head bolts.
Your heads, and intake/TB should be fine along with you pulley, all brackets, Alt, etc.
Basicially it is a common fix and not that hard.
You could also buy a complete long block for not much more and just sell off your good parts such as your heads, cam, intake, etc.
The block you have should still be fine as well.
So for another option you can take it to a maching shop have then hone it and put new piston's and rings in.
Now if you put a hole in the block this option is gone.
Good luck.
