I like your 65 S.S.Impala!
Course I'm a little prejudiced,since I own a 65 Caprice(kind of rare Impala option),65 BelAir,and 2- 67 Impala's.
I also have a 67 El Camino and waiting for an oil pan so I can put the 427 in it!
Weren't too many 65 427's---409's first half of the year,then 396 and 427's.Some with the new turbo-400's.
Yours would have been the 250 hp,327,powerglide.(I need one my self!).
Really nice car!
Mike.
