373's to 410's

dragstang86 · 10-31-2002, 10:40 PM

With the mods in my sig would you recommend going to 4.10's? Now this is my daily driver so will this really hurt gas mileage much more than my 3.73's? RPM wise how much do you think it will change at about 60mph? Most importantly is there going to be enough of a e.t. difference to even bother? How much could i expect?

thanks for the help

I would stay with 3.73 due to the lack of OD with the c-4. If it were an AOD, I'd be saying 4.10's all the way!

I'd stick with the 3.73s. Especially if it's your daily driver.
