I have a 1971 400 engine block for sale. It has been checked for cracks and acid dipped. It has been bored to 4.36 and ran and will need bored to 4.375 or 4.38. I can take it to the shop and have it rough bored to either spec to confirm block is usable if buyer pays boring charge afterwards. I just don't want to bore it and have someone want the other size. probably additional 250 in my area. 1500.00 for the block. Item is located in Des Moines, Iowa.
