My 1950 3100 runs very well but starts groaning over 52-54 mph. Am considering changing the ring and pinion from a 4:11 to something better, however, have found 3:55 the only readily available. Not sure it will be worth the work and cost to improve speed only 13%. Anyone out there have experience with this or leads on lower ratio rear end gears?
Thanks in advance for your feedback.
