A833 question

Yabut where is fourth gear? It depends on if it is overdrive or not.
Test with the front lever rotated clockwise as far as it will go; this is third/1.40 ratio in the standard box and it is fourth/.73overdrive in the od box. So that sorta takes you back to post #3....

If your 340 is gonna be a high-winding streeter, it ain't much gonna like the overdrive box. To get second gear right, you will need a rear gear no less than 4.10s. Which makes for a sick 12.67 starter gear, and a very early 1-2 shift. The second gear of 1.67x4.1=6.85 is right on. But second is good to 70mph@6000, so you never really get to use third gear, instead skipping it and going straight to overdrive at 65; which is about 2400rpm, again just right for a hi-winding cam to cruise with..
So where can you use third(direct)? IDK I never found out cuz 2400 is 47mph, a speed I am never at for more than a split-second, cuz I'm on my way to some higher mph.. So, 65 in direct gear is ~3300
But that 6.85 second gear is real fine...... it puts you close to peak torque at 45/50 mph so you can have a car full of giggly-boys and nail it with accompanying tirespin,lol.
