    Transmission - Rearend
    Just like the title says I have a 400 sbc tht "might" have 2 b used as a daily driver 2 work. Which trans gets better mpg if the round trip of the work trip was around 34 miles a day. I'm pretty sure the gears in my car are 2.73 so if anyone can throw a better # out there and a good reason why...
