You may not have all the parts but you have the most important part, all the other parts can be found with date codes in the right range. There is only one part with that VIN on it and its the engine block that you have!!The RE 327 is a 63 date coded block C-22-3 and date coded heads D-11-3 (for both). I was gonna rebuild this engine before deciding to sell it, so I could try it out. Remember it was only a long block, so I don't have a lot of the original parts that went with it. But, I do have some vintage aftermarket stuff for use with it.
