CLASS RACER FORUM - View Single Post - ET Differences Between Varying Powerglide Low Gear Ratios?

A bunch of years back when I was messing with our A/SA '67 Corvette, I had a glide with a 1.98 low. 1.94 - 1.98 always seemed to be the sweet spot. I broke the planetary at a division race and the only spare I had handy was a 1.82 geared bracket glide. Car left like a turd and lost .04 in 60', but only slowed .02 in ET. Most if not all of the .02 was the bracket trans didn't have the lightweight parts and all the other tricks. While all that gear helps the leave, doesn't really make much of a difference in overall ET.

Your mileage may vary...
