help gear ratio

[dallastx75208]

What is the gear ratio on a 62 hawk rear end? It is just the standard rear end.

[buddymander]

My 62 has a 3.54. My car came with automatic. But isn't there a tag on the cover?

[41 Frank]

My 62 Gt with 4 speed came with a 3.31, overdrive models would have had a much lower ratio.

[dallastx75208]

Mine was a three speed manual.
I think all manual cars had teh same gear ratio.

[Chucks Stude]

Overdrive or not? They have different ratios. May need to get some help, turn the drive wheel, see how much the pinion turns, and see what the ratio is.

[StudeRich]

Unless special ordered with a optional "flatland" ratio, "trailering" Ratio or performance ratio, a non-Jet Thrust '62-'64 V-8 Hawk had:

3.31 with 3 or 4 speed manual trans.

3.73 with O.D. Trans.

3.31 with Automatic Transmission, or on '63-'64: Powershift Auto.

Unless ordered with Twin Traction, it would be a standard "open" axle. A Dana-Spicer model 44, in a U.S. built Hawk with V-8.

Quote: "It is just the standard rear end." [?] [?] Don't exactly know what this means, standard what?

The easiest check, is to read the tag under the rear cover bolt on the left =Ratio, on the right =TT tag if equipped.

Hard way: you can check the number of wheel turns vs driveshaft or read the stampings right on the ring gear.

Thanks for the info. By standard rear end I was talking about it being nothing special. Just a three speed hawk with no bells or whistles.

In a technology discussion, precise terminology is everything. In theory, Stude may have build some GT Hawks with the 3-speed transmission. However, in practice, every one I have ever seen has the 3-speed w/overdrive, which would have, as mentioned above, a different rear gear ratio than the non-overdrive. Has anyone ever verified a 3-speed Hawk?

Way off topic, but hard as it is to believe, there seems to have been at least one straight 3-speed Avanti built! Why on earth would Stude have ever let that image-killer out the door?

thnx, jack vines

Nothing is as bad as 6 cylinder fastback mustang..

[63t-cab]

Was'nt the 3 speed manual the (standard trans) for Avanti?but most opted for Autos and then 4 speeds.

[Laemmle]

Indeed it was.

[63t-cab]

Think I've seen two 3spd Avantis in almost 30 years!

Tom R.'s (sbca96) Avanti was originally a 3-speed- the one he converted to a 5-speed, here:

BTW, the current Hemmings Classic Car features the big-buck restoration of a Dodge Challenger convertible... retaining the factory slant 6 auto![:0][B)] Sweet car to drive, but I've never seen one restored that didn't get at LEAST a 340!

A lot of things can be changed on a car in almost 50 years.
Don't trust the tag on one of the diff. cvr. bolts.
Don't trust the numbers and letters stamped on the axle tube.
Don't trust any of the previous owners word.
Chock the front wheels, jack up ONE rear wheel, turn it exactly 2 revolutions and count the revolutions of the pinion. If it's 3 1/3rd times, it's a 3.31. if it's 3 3/4 times it's a 3.73. If it's a tad over 4, it's a 4.10.
