If the 721 block has the recessed oil filter for the Chevy II and a 283 bore size I wouldn't let the 870 number under the timing cover throw you off. The 721 Chevy II blocks I have seen with a 283 bore size are thick. The Chevy II block that is really worth $$ is the 350hp/327 block that is cast as a I think a 362 in 1966.
