That article at the bottom of this thread says it's just 2.54:1, but with a 1.54:1 2nd gear. My T-flite expert friend, Len Schneider says that's a mis-print or typo and is actually 2.74:1....
Think about it - 1980's or so Dippy/Fury/Fifth Ave. must weight about 4,000lbs plus. Probably has a 318 with about 95 horsepower and an open rear diff. ratio of about 2.76. Needs all the help it can get in the torque multiplication department!
