So far I posted 4 Firebirds for sale - 3 in Canada that show 327's, number's matching too, several articles from Motor Trend, information from 1st Generation Firebird web site, A GM Canada advertisment, references on Trans Am own website all stating that 1st Generation Firebirds were sold in Canada with Chevrolet engines and all I get back is "misprint" and "that's not true", That's a very interesting assesment of evidence gathered from a host of independent third party sources, imo.
