rare Bigblock 57 Bel Air

A friend of mine stopped over today to pick up some parts for his Acadian and told me he had just bought a 1957 Chevy 2 door hard top.   tonight I go looking for other 57's and come across this solid  big block powered Bel Air.  I know 57's didn't come with big blocks but it sets it apart from the 235 powered cars.  This one looks like it is solid but has had some work done over the years.  1957 Bel Air
