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
