You should post pictures as it makes it much easier. Dissembled projects are heavily discounted. The non-original motor in a Corvette is a further discount. However, you could use the 62 engine to get the correct 59 engine, although that ultimately depends on what you want to do with it. Also, you probably will get much better advice specific to a vette in one of the corvette only forums. This one seems pretty active, I'm sure there are others.
