Your trans guy is right, that 2:76 rear axle will make that vehicle a pig with a 700R4. I am figuring on 29" tires on my 34 with a 3:70 and a 700R4 for a highway rpm of 2200 to 2500. There are any number of rpm calculators on the net, pick one and figure your rpm at 60 and 70 with different gear ratios and tire sizes.
