Tire 31
rear gear 3.08
RPM 5200
select th350 and show speed should be 155.7 mph

Now I don't feel so dumb, and that calculator is not compensating for convertor slippage due to fluid coupling so 155.7 becomes 132.3 assuming 85% convertor slippage (which is assuming alot, I would estimate more like 80% which is closer to 125mph)
