I have (2) 4 bolt main "512" blocks for sale. They were both running engines. Both are .030" over and have no ridge. One block is dated L 2 9 the other is dated G ? 70. The L 2 9 block has been decked, the G of 70 has not. The mains have not been touched. I will be at Fred Gibb show, and at SCR, so I can bring them if some one is interested. $2500.00 each.
