RE: 8 3/4 Diff.

[Jeff Adams <ledman_70@xxxxxxxxxxx>]

I would say it depends on how far away the track is. I just swapped out 
the standard 833 in my 64 Polara for an 833OD due to the 3:91's being a 
PITA! The car screamed, but with gear drive, Flowmasters, and 28" tall 
tires, the engine was turning 2800 rpm at 55 and it SUCKED on the 
highway! I avoided the freeeway. With the OD installed 2800 rpm is 
nearly 80 mph and cruising at 65 now is just about 2200. I lost a lot of 
power thru the gears, but the car is SO much more enjoyable to drive 
now. If I was doing the gear swap again, I wouldn't go higher than 
3:73's without an overdrive.
