These are the factory markings for undersize engine components including crankshaft journals.
These are true for a factory build but who knows what happened afterwards. Block appears a need to be decked. All 340's had the same same casting block, just the internals were different on the low compression ones. Being it needs a total rebuild, why not buy the early parts to bring the compression up to 10.5 - 1 ? Cast or steel crank will work for most builds, unless you are using the button. $300 - $500.00 would be a fair price, without the heads.
