Re: [AMC-List] T-14 Overdrive

["Jim Blair" <carnuck@xxxxxxxxxxx>]

A: I find that steep gearing works well with AMC 6 cyls. I run 3.73 with 33" 
tires and 5 speed in my MJ and it feels about right (even though my motor is 
fading a bit having surpassed the 240,000 mile mark)

Thanks for pointing the need for the 3.31 or steeper axle with
OD.
You have to be carefull not to overdo, er, under gear the car!
I run a 3.31 with T-5 and about a .8 overdrive right now.
[255/60/15 tires] So figuring this ends up geared about the same
as a 3.08 normal tired car that puts it at about a 2.46 final
drive.
It does real well with this combo.
When I put the new T5 with .64 overdrive in I intend to move up
to an S-10 two wheel drive, disc brake rear axle with 3.42
ratio. I think I may end up under egared though as this will end
up at about 2.04 final in OD. Maybe it will work with torque of
the EFI 4.0L, but now that I do the numbers I  may have to look
for a steeper geared axle. The two wheels drive S-10 axles
measure in about 54 3/8" this is about 2" narrower then the
stock American axle. I'll probably run spacers for the time
being, but as I run a wheel with 4 1/4" switching to a 3 1/4"
backspace wheel at a later date will likely happen as they are a
standard aftermarket wheel at that offset.
   If anyone needs a 3.31 American axle, I should have two
coming up for sale.
The one in the car has a sslightly turned axle tube, but works
fine, it is twingrip and complete. The spare is an open axle
from a 199 auto car, had 43K on it it is open and will need
brakes I assume as it has sat for a while now.
