I'm attempting to rebuild a vintage Hurst Super Shifter. What a mess. I got it painted black and cast gray and have to test it each time. In my research, I found an old transmission article on "Power Robbing Automatics" and the benefits of the manual gear box in racing.
Did you know it takes quite a bit of horsepower to
spin these automatics???

General Motors
Powerglide = 17 to 18 hp
Turbo 350 = 35 hp
Turbo 400 = 45 hp (holy shit)
Ford
C4 = 27 hp
C6 = 55 hp (damn)
Dodge/Chrysler
904 = 25 hp
727 = 45 hp (what the?)
Manual Muncie / Borg Warner = I can spin it through all the
gears with my hand . . .
With this baby 283 build - I need all the help I can get !
