C) drill out bolt and use an easy-outer to twist bolt(which has NEVER worked for me and I've even snapped the easy-outer into the bolt!)


Me too, and that is if the drill bit doesn't break off in the bolt first.

Welding a nut to the bolt will be your best option, though not having a welder on hand doesn't make it a real option. Is the block still in teh truck, if not you could take it to a shop, shouldn't be more than $10 for them to weld something on it.

Since you have a torch, I would spray some penetrating oil first, let it sit overnight, and then try torch and visegrips.

More than tread lightly. Leave it like you were never there, nor anyone else.
