I have a 1969 Laurentian and Im looking for parts. What other 1969 Pontiac models can I interchange parts with? It is a 350 btw. I can find tons of american model parts but no Laurentian parts :( Mostly looking for engine parts and exhaust.
depending on what you need, many parts from a 1970 Canadian Pontiac are the same as a 1969 Canadian Pontiac. And as above, the drivetrain is 1969/1970 Chev Impala.
Your 1969 Pontiac Laurentian (made by GM Canada, not the Pontiac Motor Division of GM, and as such is a Canadian Pontiac) has a Chevrolet 350 engine in it. Keep in mind, back in the day, each of GM's product lines had their own 350. Buick had one, Pontiac had one, Chevrolet had one, and Olds had one. So, a Pontiac 350 is different than a Chevrolet 350. I'd say NOTHING is interchangable between them.
But, the good news is that with yours being a Chevrolet 350, which is a small block Chevy, that's about the most popular engine design in the world, used by GM for like 50 years.
