3.31 12 bolt gears are being reproduced

I'm surprised it took someone this long to produce these. That was a popular gear, especially in the SS models.

I had 3.31's I got from Michael installed in the green Chevelle, and it was a good all around gear without having an overdrive. It worked well with the M20 Muncie out of the hole, and didn't beat the engine up on the highway. If I remember right, I was at about 2600 rpm at 65 mph.

They are proud of this though. It's about twice the price of 'standard' gear ratios.

Well its about dang time. 270 bucks though so it looks like they arent cheap. After all is said and done, your not going to notice much of a difference between these and a common 3.50 or 3.42 gear thats commonly available so its probably not worth double the price in that aspect. However, like Stan mentioned 3.31 is a great gear ratio and thats what I have in my 66 with M21. I love the accelleration and the RPM on the freeway isnt bad at all.

Even with the high price, its still nice to see someone is making this ratio again. I too am supprised it took this long to start making it again.
