Info on a 'Canadian' Nova..

[realzed]

A friend was telling me about a car his brother bought new here in Canada back in the '70's, and that he found a set of keys for it with the dealer stock tag still attached..
Is it possible to find out anything about this car - a Nova for all intents and purposes - but an Acadian model.. (from a Pontiac dealer I would assume) from this tag on the keys and info:

Vin: 14270W223517
V1223CNJ
IF54
OH 44
Thanks for any info and/or 'decoding' efforts.
He said the car was a greenish SS model and it had a 396/375 in it when the fellow his brother sold it to was killed in it - but other than that he didn't remember very much other detail..
I know Acadians are very rare but I don't know if a 396/375 would be available in one as well - if so I guess that would make it like gold these days with documentation from GM..
