1.69 low gear
masracingtd1167:
We have been talking about tires a lot lately how about gear ratio's for a powerglide ? I have been using a 1.80 low gear and I am told that I should use a 1.69 . Have any of you tried both and what did you find . Thanks Bill
Pipe Dreams:
I'll second that. Been looking at new planteries for my powerglide with differant ratios. What's the benefit of a 1.69 over a 1.76 or mas's 1.80?

I have 1.69 low in trans.No info yet sorry. I had some guy name Parks tell me DO NOT get 1.80 go with 1.69 low. I lucked into a coan max duty aluminum carrier shorty shaft with 1.69 at less than half price and had 10 runs on it. Kind of seemed like fate.
More wheel speed with higher gear getting up on tire and not as voilent is what I took as reason. Heck what do I know I just listen to those who run fast and have lots of experiance with FEDs.
retroboy:
I chose a Torqueflite because it has 2.45/1.45/1.00 thinking the lower first gear combined with 4.56 rear gears will make my converter work better at multipling torque. I'm a hand brake guy have I made the wrong choice? I want a car I can drive.
