7028273 / 7029273 Questions
 

Couple of - I hope - quick questions on these carbs

1. Did any of the later dated 8273 carbs from 1968 show up on any of the early 69 RAIV motors (late 68 / early 69 production) ?

2. What are the correct casting numbers that appear on the rears of both the 8273 and 9273 carbs ?

Many thanks in advance!!

1. No.

2. 7034973 on 8270/8273 and 7037576 on 9270/9273.

Awesome, thanks Kenth !!

I’ve owned many RAIV Pontiacs . Specifically 2- 69 RAIV Pontiacs one was a Firebird one was a GTO Judge both were original paint, all original drivetrain , and both had 7028273XX Carburetors from the factory and I had the broadcast sheet on both cars showing XX in the carb box .

Interesting, what were the build dates of the cars ?

Both cars were 3/69

That was really odd.
9270 and 9273 was specificly calibrated for the RAIV, 8270 and 9273 was not.

Would love to see the broadcast sheets on these cars!

AMA on 1969 Tempest and Firebird carb usage:

A true oddity for sure.
Maybe some of the plants were trying to blow out 8273 XX carbs.
Even stranger that the Bsheets were calling for them.
