I have the A&A 2.28 helical 1st gear in my 727; and it retains the 1.45 2nd gear ratio. This was around $700 when I bought it. It replaces the REAR planetary, and the sun gear (same sun shell). Since I bought the version with the Torrington thrust bearing, I also installed a new front planetary with the Torrington bearings. I picked the 5 pinion steel body front. The 2.10 setups I saw were way more expensive, but I like that ratio.

This did calm down the launch somewhat, along with the 4.10 rear gear and 31.8" tall slicks I run. At the end of 2014 (Oct) I put the new 540 CID engine in to replace the 511 CID. With the added torque of the 540 and the reduced nose weight of the aluminum block, the wheel stand came back. So I am adjusting for that some more. That day was 1000 ft DA, so it wasn't killer air and it wasn't bad air either. It went 9.02 at 147 mph and the sixty foots were 1.27x (3205 race weight).

I could have done without the 2.28 with the 511 and 4.10 gears, but with the new setup I am very happy I put the 2.28 1st gear set in the trans.
