I added the "427" in quotation because this car actually has a 510ci big block making a claimed 560hp, dressed in 427 trim. I'm not familiar with the AACA Zenith award this car has won, but the restoration does look incredibly nice.
It will be interesting to see how this one does - although it's been restored to a very high standard, I can't figure out from the description how it was originally optioned (including whether it was born with a 427).
