What you have, Carlo, is a low (high numerical) gear ratio in that old Dodge differential, probably 4.1 or lower, that over a short distance will equalize whatever horsepower advantage the compact SUV might have. That's why the old inline was making all that racket toward the end. The Dodge in its present configuration probably produces more low-speed torque than the Subaru. With that combination, up to 45-50 mph you can stay with the later machinery, but past 60 mph it will be no contest. A well-modified Chrysler six and an overdrive could make things more interesting on the Interstates as well as in the stoplight Grands Prix.
God's Peace to you.
