Yes, Best Machine did this for me with my 360 block about 20 years ago now. First they cook it then into the rotissory and bead blasted. They no longer do this. Make sure you get all the shot out of the block coolant passage ways thou. I must have had a lot left in mine and it chewed up water pumps for awhile. Just a heads up. The block comes out of the blast tank looking brand new.
