3.23 is a great gear I think for street driven GTOs, very noticeable performance increase over the 2.93 a very little perceptible increase in RPM.
Anyway ... for my "stock" automatic GTO I used stock logs with the ports cleaned up and the outlet opened up to 2 1/4" and a 2 1/4" exhaust system. Also removed the flapper. Hopefully that will make it breath a bit easier. |

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.
