Need schooling

Hmm, I always thought the Cadillac’s displacement was 501ci, but a quick search provided this information;

“Many people look at the sticker under the hood and think the "501" is the engine size but it's not. If you look on that same sticker, you should see where it says "472cid"......or something to that extent. There was no Cadillac 501.”

I learn something new every day!
