ft/lbs at the wheels. Does anyone know how to convert that number to the crank?

Default Is that a 3rd gear pull or 4th gear? Divide by overall gear ratio and assume 10-15% loss...
Note your stock gear ratio is with factory wheels/tires. If you have smaller, larger wheels, that affects the effective final drive ratio

Default I think he means it's a Mustang Dyno, not a Mustang Car.
Mustang is the name of a Dyno Manuf.

Default Yes - the manufactuer is Mustang Dynamometer - However
the torque number is from the wheels rather than from the crank. So its hard to determine what would be the output that the Manaufactuer use.
I'm trying to determine is there a mathamatical formula for it?

Default eh, read my post :) Assuming you did a 4th gear pull, a final ratio of 4, a loss of 15%, then
roughly 290 ft-lb peak at the crank.
