I went out and looked at an old engine today. I think this engine was taken out of a 1967 Impala station wagaon. This is a 327 4 bbl with the "power pack" heads. The heads and intake were taken off about 30 years ago and the block was set outside upside down on the ground. Today I turned it over where it has been setting in the dirt. The cylinders are rusted badly and the pistons have corroded to the point they are rough on top. I don't know if this would even be worth the effort of taking it apart??
