Re: Rear Gears

The 5400 had a 288 so a little lower axle ratio accommodated lower power output. The clipper deluxe had a 327, but ran the smaller 7.60-15 tires. It has the power and torque to maintain a higher cruise speed at a lower rpm. It appears they made up the difference with taller gears in this model. The other cars listed seem to run 8.00-15 tires and are equipped with a 327, therefore run a lower axle ratio giving nearly the same rpm / mph relationship.

There is roughly a 10% difference in the gearing between the two ratios, and I am guessing about the same difference between the 7.60-15 and 8.00-15 tires in rolling circumference.

This is just a stab in the dark, but hey, even a blind bird gets a worm once in a while.
