They never used a chevy motor in a 1st or 2nd generation firebird. The 455 was a Pontiac design and so was the 400 ,The 401 was an Olds.which was used as the 6.6. The last year 1980 or 81 had a 301 with or without a turbo. I don,t know who,s design but not a Chevy.
During transAm racing in the early 70,s Pontiac filed Homologation papers and swore a 302 Chevy (from the z28s) was installed in Canadian Firebirds so they could race with the better developed engine with a Firebird wrapper.
No Firebirds were ever built for Canada with a Chev engine but they weren,t challenged on it.
There were Canadian Pontiacs built with chev engines, A Chevelle was built here with chev guts and a Pontiac grill and sold as a Beaumont. A Cdn full size Pontiac was an Impala with a Pontiac label, and Chev engines . But never a Firebird.
