I have the TKX with 2.87 1st/.81 OD. 467 cid, 3.31 rear, 27 inch tire.
I totally respect FJs comments and I'm sure you would not go wrong with his advice. But, I think it depends on how you drive the car. If you do a fair amount of driving, cruising at 75 or more, then the .68 OD is probably a good idea. If you rarely cruise that fast for prolonged periods then the .81 would be as good or dare I say a little better. The roads I drive on are 55 mph roads. At 65 mph I'm at like 2100 RPM and I can do that all day long. 75 mph is around 2500 and is still very comfortable. I think if I had the .68 OD I would use it less, but maybe I'm wrong. But, I'm very happy with my overall gearing. You could also do the 3.27 1st/.72 OD. But even with the 2.87 1st, traction is an issue so I'm not sure how the 3.27 would do.

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.
