Does anybody have a Pro Trans list of letter codes and available gear ratios?

Edit: I found the link in the fine print on their website.

Just FYI that on insidecompracing.com you can go to the classified section and generally find some 904 gear sets and trans for sale. Many of the comp folks run Pro Trans.

We use Pro Trans. We like the 727 SB more than the 904. Has a few different parts and deeper pan doesn't hit the rotating assembly. You probably need a 2.65 to 275 first.

I’m thinking 2.75 I want to get off the line much quicker than I am now.

You can try 2.75 inexpensively......They came factory in many late model
904s. They are not straight cut BUT a Huge improvement over 2.45 in a small block.

Pro Trans just did a 904 for my Aspen with a 360. He decided on a 2.61 first and 1.61 for second gear.
