The 2.45 or 2.66 1st gear will be fine for you. Big cubes, lots of torque down low. The 3.09 was a 6 cylinder trans only to get that little thing moving. I don't think it was any weaker than the others per se but you won't need that steep of a 1st, plus as Fred said, there is a bigger spread between 1st and 2nd.
