67 Pontiac Grand Prix Convertible 428 HO M22

My dad bought a brand new 428 Bonneville wagon for my mom before he left for Vietnam. There were six of us kids. So I’m always looking for a good 67 Pontiac. This one is a little out of my price range but very cool.

The engine callout sticker on the air cleaner is incorrect. No sticker is correct. Pontiac didn't put engine callout stickers on their performance cars until the early 1970s

Pontiac did not offer the M22 in 1967. Should be the same as the 428 HO 2+2 which was either an M20 or M21 which was only available with the 4.11 rear. 3.23 gears would get the M20

I didn’t think the sticker looked right. And I should’ve known about the M22 because I don’t think it was even offered at that time. I guess I’m not surprised that dealer would pass off wrong information like that.
