This is a fresh machined but once assembled 4 bolt main block. Built it for my Chevelle, but I had the wrong casting date for mine. Pictures show it being disassembled because I wanted to list it by the weekend. As well known, you only get the right casting date once! That's why I'm doing a block twice...You will be getting a 100% BARE block! Everything else shown in the pics is going on my new build. Has NEVER been fired up. Bored .060 from 396 specs. Will have cam bearings in it and main caps attached. Sold AS IS! Buyer arranges shipping if required.
