Yep those fall right in line with the gear multiplication of the 2.20 x 3.55's I mentioned that were also available and stating that was about all GM would recommend in one of my previous posts, however the combo wasn't recommended and seldom sold. I have one here, it sucks, lol.
On the extreme of no torque, 2.52's and 3.07 gears were also offered in 1969 on the Z28 order sheet. Can you imagine a little high strung 302 with that? Not the best scenario, and as a result research has indicated that about 1 in every 5,000 built even bothered to check that off. So out of 20,302 69 Z's built, it's estimated 4-5 got the 3.07 gear. Just not a popular deal. |

We did 3.55's in my buddies built 461. Runs excellent! 11.56 at 115 mph. Tires were 28".

I have a M21 with 3.31, Seems OK for now. Would love to put in a M22Z.
Didn't 454 LS5 Chevelles come with a 3.31 gear and a M21/M22?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
