i have a 200-4r and love it! great low gears for fun , the 4th is .67 od. its quite a drop in rpm even without a lock up converter. i may change to a lock up next year and a little higher stall. even with a posi 3:55,, traction is a problem, well can be a problem ;-) Once the tires are hot it launches well!

oh and my speedo cable is at the very rear of the trans, i used the 61" cable routed over the subframe run along outside of the subframe to a hole near the brake cylinder.
