In order to alleviate a severe off-idle bog, I need to replace the rear-end gear in my 1968 Camaro.

Car has a 350cid, 10:1 compression, Edelbrock Performer RPM Heads & Cam, 800cfm Carb. TH350 with a 2200 Stall converter.

Car currently has a 3.08 rear gear in a 12-Bolt Posi unit.

What would the board recommend? 3.40 or 3.73?
