Never said to lay UNDER the car and watch the driveshaft,
Wayne. It's easy enough to look underneath the car while knealing BESIDE
the car and see the point of the wire tie to see when it gets close to or just
after the third revolution as the tire makes a full revolution. After
all, you have to have the 2nd person stop you at one tire
revolution. Unless you have a 4+ gear set, the tie is going to be real
close to where it started (pointing straight down) to determine its final
position at one full tire turn and will indicate a high 2+ or very low 3+ gear
ratio.
It's not like the fella that wanted to take the hood off
his car and have his buddy ride in the engine bay and look down the carb to
see if the vacuum secondaries opened at full throttle. :*)

Here's another method you can use and takes two
people. Get a large wire tie and snug it around the driveshaft with
what's left pointing down (6:00 position) as a reference, i.e., don't snip
off the end. Make a chalk mark on the tire at its lowest point on
the ground. Carefully push or drive car one full tire revolution
while 2nd person watches the wire tie on the driveshaft and counts the
full revs. When the tire has made one full turn, look at the wire
tie. How many full turns did it make and where it is now in relation
to pointing straight down. Did it make just over 3 turns - could be
3.07 or 3.08; 3 1/4 turns - 3.23, etc. That will get you close to the
final ratio with whatever wheels/tires are on the car
now.

lol.. when I first bagged my 64, I had a popping noise when raising the rear passenger side.. to figure out what was happening...I put the axle tubes on jack stands, laid under the axle, and had my wife raise and lower the car so I could see what was going on.. It wasn't a very good feeling, considering my car does not raise slowly at all... Oh well, at least I figured out where the noise was coming from..

To Funny Dale... a local guy
bough a set of slotted mags at a yard sale, to match the ones he had on
the front.. He jacked up the car ( ONE SIDE) and removed the rear tire and
mounted the mag.. He then used scotch red and green sanding pads to clean it
up.. and then polish it while it spun with the car running in gear.. Both wheels
wee polished in no time and far outshined his on the front of the car So
while he was at it , he removed the front wheel and put it on the rear and
started the eng. put in it gear, and was set to polish away... only ONE
problem these Mags had tires on them with valve stems.. rotating a high RPM.. he
picks up the red scotch pad and folds it over his hand and pokes it into the
spinning mag. WELL a trip to the Hosp. and came home missing his
ring finger.. DUGH !
A good plan
went astray

Ok guys, thanks for all the
feedback...
I figured out a good way to do it..
hooked up a tach, had my wife get in front of me
in her truck and do 60...
I took note of the engine RPM's at that
speed...
then did the same at 70...
doing the math... 2900RPM @
60MPH=3.27 gear ratio
and 3350RPM @ 70MPH =3.25 gear ratio
So, I believe I have a 3.23, per the list from
Tom...
(thanks tom)
What do you guys think about that RPM?? Is it too
much?

Re: [Chevelle-list] rear axle ratio??
Title: Message
I might be mistaken but the rear used in 55-64 was
a Hotchkis type and the the 65 & later featured a Salisbury
rear.
However,I might have the designations
backwards.

RE: [Chevelle-list] rear axle ratio??
Title: Message Here's another method you can use and takes two people. Get a large wire tie and snug it around the driveshaft with what's left pointing down (6:00 position) as a reference, i.e., don't snip off the end. Make a chalk mark on the tire at its lowest point on the ground. Carefully push or drive car one full tire revolution while 2nd person watches the wire tie on the driveshaft and counts the full revs. When the tire has made one full turn, look at the wire tie. How many full turns did it make and where it is now in relation to pointing straight down. Did it make just over 3 turns - could be 3.07 or 3.08; 3 1/4 turns - 3.23, etc. That will get you close to the final ratio with whatever wheels/tires are on the car now.
