I just finished installing 4:11s in my 53 flatbed. And though I haven't attempted any new land speed records as yet, it really accelerates noticably better than with the old 4:56s. My next move I believe will be for taller tires in back.

I think this should put me at just about the limits of my bravery with the old flatbed, bias tires and a front end that needs rebuilding.

BTW, I'm running a '54 235, toilet bowl carb, dual exhaust with orginal 4 speed.
