Got a 9: finally
« on: April 26, 2010, 05:04:29 PM »
I just picked up a 9" for my mach 1. I am having the it rebuild with 3.25 gears, limited slip, new bearings the whole bit. Should be nice when its all said and done.

I'm surprised you even found one.  The 3.25's will be great street gears....good choice.  Let us  know when she's in and how it feels.

Tim  sorry I don't remember which tranny you have, are you still installing a 5 speed?  If so you might want a higher ratio like 3.50 or 3.89

With my 73 and 3.50 gears, driving on the interstate at 70 was a bit obnoxious.  the 3.25's should be fairly nice depending on your choice of tire size.

From the specs on your engine build you should have plenty of oomph to make those rear tires light up well into second gear even with the 3.25 gear.

Now when I had the 4.11's in the car, highway driving was not only obnoxious, it was downright unpleasant, but the car sure would scoot around town.

Yeah there were a couple reasons why i chose the 3.25's. The biggest being the free way driving. I still want to be able to drive the car haha. The second is that i was afraid that if i had anything too low i would just spin my tires (seeing as these cars have no traction as it is).

You've got the no traction down right.  Even my 65 289 with 2.73 gears will squeal in second gear.  3.25 will be just fine for you.

Yeah im hoping that if i add some 5 leaf springs that i will get better traction because i REALLY don't want to add traction bars. My uncle had a 71 mach 1 back in the day and he said with all stock he could spin the tires all the way through 3rd occasionally haha so it should be fun.

I put the 5 leaf rear springs on mine and it raised the back of the car a little and made it ride much better and you can actually carve a turn to some degree, but traction improvement?  Nope-you won't see that at all.

Yep, My dad had a 65 coupe 289 HIPO(got stolen) :( and it was a 3 speed. He said he could dump the clutch in first or second and just donut all day. He loved that car.

5 leaf springs won't give you more traction.  Traction bars is the only way to improve traction.

Hi-Po Mustangs in 1965 only came with 4 speed, close-ratio, top loader transmissions. Farlane Hi-Po's in 1965 had an optional C-4 3 speed automatic transmission, Mustang got the C-4 in 1966. No 289 Hi-Po Ford of any type, Fairlane, Falcon, Comet or Mustang, came with a 3 speed manual. transmission.

Thats what i thought... but he swears it was a hipo 3 speed. So i dont know if somebody put a hipo in a 3 speed car or they put a 3 speed in a 4 speed car. He says it was fast as hell and it definately was the hipo solid lifter motor.
