Mine was a "warranty" block with NO VIN stamping. Block was originally in a 1970 6bbl 'Cuda that evidently had the motor replaced long ago"?" I purchased the short block from a friend as he had found an "F" 1970 block that he felt was more "correct" . I put this in my 1970 Challenger R/T Sixpack because it had the correct rods , balancer.......
