The 1.57 is the overdrive,i beleive the 200 uses the same planetary gearset as the 350.

TH-200-4R 1.568 = 157 which is the same as the one in the tool box i had just put a more exact ratio instead of rounding up

yes the 200 and the 200r4 are the same ratio because the planetary gearsets will interchange, and they are not the same as 350

tci makes a valve body and hollow converter setup for a t-350 now you might want to look into that.

are you sure your tach isn't set on v6? i ran a 3.23 with t-350 last year with 80 in tires on a 1/2 mile and couldn't get it to turn over 5800
