402 block casting number 3969854 dated in August of 1969 and is .030 over. Block had two sleeves in it when purchased and had to put one more in due to a pin hole in the middle of one of the cylinders. The block was cleaned and magged and has not been holding the pressure at the top of two of the cylinders with small leaks. The guy at the machine shop told me it could have some cement put in it or possibly take the sleeves back out and try again. At this point I have almost $700 in machine work along and paid a lot for the block as well. I will take offers on the block is somebody is interested and can take pictures of it as well. Shipping is not a problem and can be reached at 330-770-2517 for any questions. The block I believe might have been lightly decked at one time so the numbers are faint and the head bolts all have heli-coils in them as well.
