Default Re: rear gear ratio

With an AOD definitely go with the 4.10's. I have 4.10's in mine with the 5 speed and I get 12 mpg with that 750 holley atop the intake. I am thinking of making the switch to 4.30's or 4.56's. If you have a 5 speed, you may want to step down to 3.73's as first gear in a stock t5 is nearly useless for driving around town.
