be VERY careful guys with heat on a block side. it's fine to heat the brass, and it's fine to get a bit of heat into the block, but IF you are going to be setting a torch in a rig to maintain heat for a long time, BEWARE!!! cast iron will crack. it will get hot, and cool too quickly and crack. I would not get the block anywhere NEAR red hot. and if it cracks, and you "drill the ends of the crack" and try to weld it, you will be looking for a few more cracks. you can gas braze brass solder a crack, but it's really not a good plan. better plan is to keep the heat moderate, and never get the block near red hot.
