still in the crate after all these years, 427 ZL 1 that hasn't been used yet

In an unbelievable discovery, an NOS (New Old Stock) version of the bare engine block was discovered while answering a Craigslist ad for Chevelle parts. It was found inside the original plywood crate, exactly how it was purchased from Chevrolet and stored in a small garage closet in rural middle Tennessee in the early 1970s. Even the plywood crate was still in mint condition and still bearing the original Chevrolet Heavy-Duty Parts 3952318 ink stamp.
