The last straw!!!!

I just picked up two stock titans and a motor plate cheap. Now I am hoping to get my trans tomorrow so that the only thing that I am really down is my slipper clutch, spur gear, pinion gears, & the EVX or Novak SuperDuty. I am just trying to figure out what gearing should I start out with on my project. Any help you can give me would be most appreciated.

Thanks,
Lee
