rarest small block intake manifold EVER???

From the ebay auction.

Very rare Edelbrock STR12 340 crossram manifold. I bought this from a guy that raced a 340 Dart. The original top cracked from a backfire but there was absolutely no damage to the bottom half. He had a new top custom made that is much stronger than the original and had no more problems. The ports are unmodified and will fit a stock 340 or 360. Linkage included. Also includes nice original cracked top, that can be repaired. On the shelf for a while, very dusty. No Reserve. as is. See my other auctions.
