The Catalog of Canadian Car ID Numbers lists a convertible 1963 Parisienne V8 ( doesn't say which size V8 so I suspect a 283 ) as having a curb weight of 3610 lbs
It also says that a 1963 Impala V8 convertible weighs 3620 lbs. ( Again I suspect this would be a 283 )
Baed on this it appears that a similarly equipped Impala is 10 lbs heavier than the Parisienne.

I'm surprised that the next generation (1965 and up) is so much heavier than the 1964 and down. A loaded big block Chevelle is not much lighter than an X frame B body.
