276 REAR END RATIO
With a 276 rear end ratio you should be able to wind 1st gear to 55
to 60 MPH. At that speed the shift into second gear will snap your head a
little. Second gear should be able to wind to 85 to 90 and it will shift
into high gear even if you still have the second gear button pushed in.
Then as you slow down it will downshift into Second gear. Safety feather
built in by Chrysler Corp. that most guys don't even know about. When we drag
raced we would special order from Chrysler Corp. a special high
speed police pursuit governor weight that would hold the
transmission in second a little longer for better performance. Then it would
still shift in to high gear no matter what button was pushed in. Also-----you
can hit the reverse button at any speed above approximately 20 mph and it
will just pop back out and nothing will happen. Don't try this now that the cars
are 50 years old but it worked perfectly back when they were new.
Also, if you go taller from 8.00 x 14 inch tires to 9.50 x 14
or even 15 inch then your older Mopar will sit higher in the back which
will accent the look of the fins and make the car look fresher. ( like new
springs) The 2.76 rear ratio would now be about a 2.54 rear which is the
highest gear Chrysler made. Your gas mileage will improve but your cornering
will suffer a little due to the high center of gravity in the rear
end.
