what would be the best aftermarket gear ratio for an automatic 98 ss camaro?
I ran on a stock motor with 3:55, then went to 3:73. I didn't run any better times with the 3:73, so I went back to the 3:55s. This was on an 1/8th mile track. However; I would recommend the 3:73 for a good all around gear for a 4L60E. If you had a T56 I would say 4.10, But not on a 4L60E. I have seen this done before but they were not happy with the highway RPMs. 3:73 should put you at 2100 RPMs @ 70 mph.
