If you have an arc welder at your disposal, you can hook the ground to the block and connect the stinger clamp to the broken stud. Set the heat to about 100 - 125 amps. Turn the machine on for a few seconds. This accomplishes two things. One is burning up the rust between the bolt and block. The other is generating a great deal of heat without using a a torch and adversely effecting the area around the bolt. At this point, because you have a fair amount of bolt protruding, I would get a nut that slides over the protruding bolt shank and weld it on the end. When the weld cools, but the bolt is still quite hot put a wrench on it and begin to work it out. If you don't have access to an arc welder, you could at least do the weld the nut on trick with a 110v. MIG welder. I am sure someone would probably have one you could use if you don't have either an arc or MIG welder.

I would be very careful to not destroy the protruding end of the bolt because you are then just about stuck with trying an easy out. I agree 200% with Dave on the drawbacks.

I think you will get it out.
