need confirmation from what ive been able to dig up in the ls1tech archives ive gotten 1 answer. the 99 t-56 gear ratios are as follows: 2.66, 1.78, 1.31, 1, .75, .5 ? anyone able to confirm this? with my calculationsthat puts me at 106 mph at 5800 in 4th, 109mph @6000, and 112 @6200. i think i may be in a bit of trouble when i make my first quarter mile pass........
Try this calculator just select 98 f-car M-6 modify tire size, gear ratio, RPM if need be.;

But if you wanted to calculate it yourself you would have to first find the circumference of the tire.
C = pi*diameter
C = 3.141...*25.66 inches = 80.6 inches
since you want your final answer to be in mph, you could convert that into miles
80.6"*(1 ft/12")*(1 mile/5280 ft) = 0.001272 miles/tire revolution
So to find what speed you would be doing at a given rpm you would have to do
Engine RPM * (transmission output/transmission input) * (rear output/rear input) *(tire circumference/rear output)*(60min/1 hour) <--since you want mph, not miles per minute
So that would be
6200 RPM * (1 trans output rev/1 trans input rev) * (1 rear output rev/4.10 rear input rev) * (0.001272 mi / rear output rev) *
(60 min/1 hr) = 115.5 mph
Sorry if that got kind of confusing
