The decision is made

i'm not towing anything so thats not a problem. i feel no need to split gears. have you split gears going down the quarter mile? just curious. i know guys that have a GV and they like them. i have nothing bad to say about them. but i want more of a OD ratio from a OD.

from the calculator i'm using it says i can use a 3.55 and the .67 OD tans for about 80mph at 2300 rpm..

the car will get a 408 sooner or later which will be built for tq. power range from idle/1500- to about 5500 range so i'm not too worried about the OD being a big jump.
