Default how do you figure top speed in a stalled TH350?

I know to use the MPH calculator for an M6 but how do you figure it out for a TH350?
I'm going to have 4.10 gears either a 26" or 28" slick and a turbo action 8" 4800 converter.

it is still the same 1/1 final gear ratio. go to the fbody gear calculator and use the A4 tranny but look at the third gear numbers. its all about the tire size, rpm, and to a small extent the convertor slipage/efficiency.

Yeah but how much difference does the converter slip make? if you calculate it out i should be at 123 mph at 6500 with my 4.10s in top gear. but after you factor in the converter slip how much will it go down? basically i want to be able to do 120 in the 1/4.

Its kinda hard to say how much slippage since it varies from different converters. On mine I am running 26's with 3.73's, hitting 121mph at about 6300rpm's in the 1/4 mile if it helps you any.

Thanks man i guess i'll just have to throw it in and see. his is pretty much my first auto i've ever had and am learning everything i can about them. I know EVERYTHING there is to know about the T56 but that could no longer handle what i was going to do.

You won't be sorry man. I am very pleased with it. IMO its more fun to drive than the M6 on the street and at the strip. Its more consistent and more forgiving (no missing gears). I also swapped from the M6.
