Going from a 3.06 first to a 2.48 first is one heck of a change. I think that it would show up way more on a n/a engine like you said. I know one thing that the deep first gear works well when towing a load. Our trailblazer really uses the help of that 3.06 gear when getting a extra 6k of boat moving from a dead stop. By winding out first a little longer the drop to the 1.63'in second is not so bad. In second I can maintain 55-60'mph all day long going up hills. I would bet that simply,buying a 200-4r would be just as cheap as that gear set for the 700. Jay6155
