350 vs 200r trans

I currently have a 350 trans in my 69 Mercedes 220 and would like to get something with a higher high gear. This car has a 4.08 rear and turns a lot of R's on hiway.
I need to know what I would need to change to make this switch and how high can I get high gear?

High gear is always 1:1. What you need is overdrive. The 200-4R is .67:1 overdriven, 33%.

The overall length and output spline is the same as T350.
Use the 200-4R converter. You will need to fashion a correct TV cable, bracket and throttle linkage. Get a dipstick and tube. Mount will be moved rearward

Don't forget the lockup. It helps 10% on mileage.

I went from a 200 to a 350 and it was a straight bolt in. I recall the frame already had holes for the mount relocation on this GM G body.
