Street Gear Poll

OK, Been driving around in my toyota tundra with the overdrive off to see what I think about 3.91 gears on the street/highway.

My trips are about 20 miles of 70 MPH driving. My truck rolls along at about 3200 RPM at 70MPH. IT has a VVTI V6 in it.

My plans for my a body are a mild 318 with a low first 904 and custom converter. Whatever engine goes in is gonna have a hyd roller. Exhaust will be quite, but dont let that effect the poll. However keep in mind that priority will go to the gear, and the exhaust can be quieted down if necessary. There is plenty of ways to get rid of the interior drone if you do enough research.

And also please remember this is not a cross country car. The idea is to leave the country haul butt and have fun on the way, burn a ton of gas, upset all the hybrids, rice burners and chevys and go back to the house in the country.

EDIT: Lets assume a 28 inch tall 275/60R15,
ALSO, i intended for this to be a very general poll. Not something to decided on what exactly gear I should use on this car. Personal experience is the main factor. IF you had a car with 4.10 gears and wanted more then by all means post.
