A-833 2.47 1st gear change to 3.09

3.09 gearset will swap into your cases without any other modifications. I run this gearset in my 72 Demon, with 3.23 axle and 27" tire. Bumpy cam in a very mild 360 SB, and it drives really well. I can easily maneuver the car at idle. I have plans to either put a 2.94 gear in the car or get the tire height up to 28".
