That is a restamp without a doubt. The CE block assembly code is located on the starter pad and this one is T089 as seen in the pic. Aug 1969 is when it was assembled and the block was cast July 9 1969. make sure you check the bore since the 854 block was used for the 402 vs 396 in 70. Some late 69 854 blocks were bored to 396 and in 70 they received the C proceeding the engine suffix code indicating that they were the 2nd design 400 CID engine (402), pic attached of the note from a parts manual about the pistons.
