Gear ratios

[62champ]

As a self confessed "gear head", I always trying to dig into the minutia of everything that I am interested in.

With that being said, does anyone have the numbers for all six gears for the tranny found in the FIST? And just for good measure, what the "pumpkin" ratio is as well.

Thanks ahead

Thanks - really did not expect to see such quick replies.

With such a deep 6th gear, like the fact it is has such a high numerical "rear end" ratio. Have had quite a bit of experience with older cars with Borg-Warner overdrives which give a .7 to 1 final drive ratio. Have a 1/2 ton truck with a 4.27 rear end ratio - the .7 overdrive really allows the motor to take a nice deep breath and roll down the road at a much more manageable rpms...
