maybe to count correctly and get rid of that trac-loc problem he could spin the driveshaft and count wheel rotations till DS was one full rotation? this seems to me like it would make both wheels spin the same number of times?

sunil6784 · Nov 6, 2005

Use a piece of chalk on the driveshaft...

FordRacing302 · Nov 6, 2005

This is exactly how I did it...I jacked up the rear end and taped a part of the wheel and a part of the fender parallel to each other, I was going to tape 1 side of the driveshaft but i found an unusual mark that I used for reference...I turned the driveshaft by hand 1 complete rotation while watching the wheel and by the time the DS had completed its rotation the tire was only 3 quarters the way around...

Now if there's an error in the way I checked it then tell me how to do it, so I can go check what the ratio really is

FordRacing302 · Nov 6, 2005

BTW, The car has not run since Ive owned it, so I have not gotten a chance to check out the RPM's at certain speeds

jstang209 · Nov 6, 2005

u turn the wheel and count the DS turns..

Slo 5.0 · Nov 6, 2005

take apart the rear and count teeth if you really want to be sure.

I gaurantee that I didnt miscount,

sorry but i guarantee you did.......

you can't even buy a ratio of that size, and i think you could hardly get the car to move if you did

the smallest gearset i can find from 2005 to 1965 is 2.35

FordRacing302 · Nov 6, 2005

Well tell me this, Is there anything wrong with my method of testing??? If so, what should I do to find out other than take off the cover?

You probably counted right but you didn't perform the test correctly.

Listen, Jack up the rear end of the car. Mark the tire and wheel well accordingly.
Get under the car. Mark the driveshaft with a marker or chalk or whatever. Have someone else spin the tire 1 complete turn , while you are under the car counting how many times the DRIVESHAFT turns.

Michael Yount · Nov 6, 2005

Wrong way to do it -- get a friend to help -- have him/her rotate the TIRE 1 TIME while you count driveshaft rotations. Use the right side tire and be sure both tires are off the ground. MARK THE DRIVESHAFT -- it's simply too easy to get confused with other 'unusual' marks that look the same.

FordRacing302 · Nov 6, 2005

well since I was using the left side wheel and turning the DS then I guess Ill go retest real quick, Ill post my results here in about 5 minutes

jstang209 · Nov 6, 2005

yea like I SAID u were doing it wrong lol.. u were counting the tire rotation while spinning the DS.. its the other way around

FordRacing302 · Nov 6, 2005

Ok well I did the test "the right way" and came out with the same results...except maybe its a little lower like 1.90:1 lol...Either my differential is toast and is giving my wrong readings or I really do have high ass gears...

It might not even be a 7.5 rear end, no one ever told me it was, I just figured so maybe you guys could tell me here's a pic

this is kind of off topic but did you ever notice all the 2.3 mustangs were giving the 3.73 rearend, they are so weak they cant use a a 2.73 rear.

imagine how slow a 2.3 would be with 2.73 O_O

WHAT?!?!?
FoxFan is at it again.. 2.3's didnt come with 3.73's..... unless its a Thunderbird turbocoupe....

my buddies old capri did....w/ the 2.3

HISSIN50 · Nov 6, 2005

I dont want to bash anyone - we want to help you find your real ratio. But even by the method you used in post 24, the ratio you guestimated does not match the numbers you posted in that post.

Good luck with getting it figured out.

Interesting... but as Foxfan said "all" 2.3 come with 3.73's....which they dont and never did.

well i was told a while back a 2.3 had 3.73s or at least my old A4LD stang. I never got in depth with the 2.3 scene as i got a v8 stang.... but i know that alot of the smaller motor cars had much steeper gears than a v8 stang... they need them to move.

but i've always thought the came with 3.73s

Have you ever heard of these gears??
