so that about sums it up. Last bolt to lossen to take off the supercharger. SNAP! Sheared the head off. Good news is that i have a lot of room and there is about 1/2" sticking out. I was thinking of welding a nut on the end of it . The heat would probably loosen the thread. My question: Is this safe? Could the heat hurt the block? And is it safe to to be welding under the hood? I dont want to blow my self up! Thanks
