    4.10's with BFG KM's turn right at 3k at 70mph on a slush box. You will tun less with the manual. Personnaly the I6 would do well with a little more gear like 4.56. My 350 is a little tired and around town it's a little low on power as a result. It could use the 4.56 as well but I have to take a little loose for hwy.
    http://www.ring-pinion.com/calculators.shtml will let you see what your RPMs will be with different gears and tires.

    I'll second the vote for 4.56's w/ an in-line .
    That is the tire and gear combo that I am going to use also.
    I drove a truck w/ a 250/465/208 and 4.56's w/ 35 BFG's and it was great. It still handled hwy speeds and had good power around town as well.
    In my opinion if the motor is healthy than it will take the extra RPM on the Hwy for any length of time.
