Standard bore small block Chevy 400 2-bolt main block, plus crank, rods, and balancer. The crank is also standard size, it has not been ground. Block has casting number 330817. No corrosion damage to anything, it has been stored inside since disassembly. This is a matching set of components, these are all the same rotating parts that came from this complete engine assembly when I took it apart for storage. Rods are still attached to the pistons and are all boxed up, so I didn\'t include any images of them, but I can do that if you need to see them. I picked up two of these many years ago, and rebuilt one of them for my truck. After sitting on this one for nearly 20 years it is finally apparent that I will not need to do that again, since the rebuild on the first one is still running strong!
