Darryl, given the 403's lack of torque below 48-50 mph, I usually manually
downshift at about that speed if the top of the upgrade is not in sight.
But with the 3:70 final drive gears, my 403 will not lose speed on anything
less than a 6% grade. It is the best performance upgrade that you can make
for the money spent.
