Engine Stamp Pad Questions

There is no exact measurement with the maltise cross. It just means the crankshaft is undersized SOMEWHERE. Either rods, mains or both. Could be .001" Could be .030". I've torn down enough to know. Undersized is all it means. Also, don't be surprised to find rods "numbered" with playing card suits. Hearts, clubs and the like. Seen it a lot.

Nothing wrong with 8.5 compression or a cast crank if it has both. Build it. It'll be a good engine.
