Ok, I just read the 1972 Pontiac service manual. Page 6B-59 states that the outer ring is removed on 455 HO carbs. I compared the text of most of the chapter and it is a direct carry-over(reprint) of the 1971 Pontiac service manual. I believe, and hopefully Dan will agree, that NO 1972 455HO Q-jets were of the 800cfm variety. I have seen quite a few 72 455HO cars and I know that none had the 800cfm carb. I was under the impression by experience (and from the factory service manual) that the non-booster ring 71 Q-jet was available on the 1971 455HO. I didn't think that the non-booster ring 800cfm carb came on any other Pontiac that year.
