From what I’m seeing the most guys using a 3 speed
With a aggressive rear axle ratio and a trans brake have trouble
With the 60’s Or from what I can tell anyways
You use a 904/727 or a glide whitedart
I have both a 904 and a Powerglide.. I think the issue is shocks. And Springs.. I believe it was Al that said by the best shock you can afford and I agree 100%.. also have worked with John Calvert with getting the correct leaf spring for my car..
Shocks and springs and tuning are critical to getting the best from your combination. But if the combination (i.e. low gear ratio) is out of whack, one way or the other, it becomes difficult or impossible to get the car to run as quick as it's capable of or even control the tire. The suspension and transmission parts - including available gear ratios, tuning, converters and tech, coming out of the very high horsepower Pro Mod and drag radial world, is crazy. All about tire management.
