Hello David, Thanks again for the pictures of the injector removal tool. I lucked out tonight and found a special "wrench" for putting cut-off wheels on my air cut-off tool. The tool is just the right thickness and just the right size to fit in the injector slots. I was able to use my little slide hammer with the two ears to get under it and pull the injectors. The all came out (eventually). After hearing all the horror stories I consider myself pretty lucky. They look in good shape except that the tips are carboned up. Now about your rock. I remember my mother telling me about the time when my parents built their first house. There was a large rock (probably granite) that was uncovered in the basement. My Grandfather told her to uncover the rock and build a fire on top of it. Let it build up a nice bed of coals and the rock will crack. Apparently this worked for my folks. I imagine the type of rock makes a difference. A sedimentary rock like sandstone would probably not crack but something with a crystaline structure to it like quartz or granite ought to crack under heat. Another poster suggested building a fire under the rock, getting it really hot and then pouring cold water on it. That oughta do it. The only problem you might have is getting to the bottom of the rock. I'd imaging building a fire along the sides of the rock would work pretty well. I don't know if the 450 will be much help. It does not take much to lift the back of my 450 up in the air. Granted I'm missing the rear weight but still it may be a stretch depending on how big the rock turns out to be. Let me know how it turns out for you. I'm getting ready to clear land and build a house with a basement. Lots of big rocks around here too. As a matter of fact there is a quarry only a few miles away. I may end up with the same problem as you. Best of luck,
John
