TKO 600 failures?

[Jim Vander Wal]

3.27 rear and .64 OD by choice. I like it and wouldn't make a change to the .8 whatever it is. Started with 3.73 gears and switched, never looked back.

That said I'd like a 6-speed to have the option of the two ODs and better shifting. The .8 5th gear would fill the long jump between 4th and 5th.

80mph at 2,200rpm worked well for my cross country cruising. I used 4th if I wanted to go fast, easy 140 and 150+ was possible.

My new FFR build will be 3.31 gears with same engine/trans combo.

It might make a moments worth of sense to decide on a few parameters first:
What do you expect?
How to you drive or plan to drive?
Distances or type of driving?
Racing - HPDE, auto-X, road racing, drag racing?
Engine and power bandwidth?
Tires and sizes?
Do you want to shred the tires on every take-off?
Would you like a first gear that will actually work in town or is starting in second OK?
How fast do you want to cruise on back country roads?
At what speed are you comfortable on the expressways?
I think engine performance has a lot to do with the gearing selected.

The "best" is rather academic as everyone lives with different parameters, performance and expectations.
