Single vs. Double; Original vs. CE Block

To me paperwork is the most important factor. True GM paperwork is still difficult to duplicate, long after we are gone they'll be stamping "restoration " motors, but the paperwork will determine the true heritage of a vehicle. Today, I heard about a very desirable '67 Corvette roadster, 435, sidepipes, original bolt on's and rare color. It is a vehicle that has a proven ownership history and original engine, but no paperwork. I'd rather a lesser vehicle with paperwork.
