This question has probably been posted many times, I've read som but are not clear, so forgive a newbie: how can I tell for sure if I have a 289 block or a 302 block in my car. The engine is matching number c-code. Car produced last week of GT/CS production. And then for the follow up: if 302 blocks were used to set up a 289 is the difference bore or length or both?
