I have a 305 engine with 2pc rear main seal block, has clean edelbrock performer manifold and nearly brand new Holley 600 carb with manual choke. I just pulled this from a project car this past March 2010. It ran fine with no issues, mileage is unknown . It also includes plain chrome valve covers that came mounted on it. It also includes the distributor.Casting #s are 460778 -block, 376540 - heads. Can be inspected locally in Norwalk CT 06851. $300 PM me if interested. Thanks, Craig
