1) you have to look at the overall or effective gear multiplication and ultimately the size of your tires as well.
Just an example. A car with 3.73's and a 28" tire will have the same rpm characteristics (for a given speed) as a car with 26" tires and 3.47 gears (which don't exist, but theoretically, it'll be similar to a 3.55 gear).
Basically, the bigger the tire, the more multiplication it takes to remain comparable.
2) As recommended, you should run the car with the gears in it but you're most likely going to blow the tires off in every gear with a set of 4.10's out back (even with the taller tires) cause the MT has very short gearing (3.66 for first, vs 2.66 or 2.97 for a typical 6060 or Magnum). Your taller tires are helping, but yes, you're probably going to find that the car is on roller skates with a final multiplication of 13.4, even with sticky, tall tires.
To put into perspective, a typical Magnum or 6060 (let's say the 2.97 wide version) with 3.73 has a final multiplication of just over 11.
Running 4.10's in a MT is like running 5.05's out back for a 2.97 1st gear trans (like a 6060 or Magnum). People would think you're nuts running that high of a gear with a blower.
Again, tall tires, sticky tires will help, but only so much. Drive the car and see, but I think you're gonna find it won't hook in the first 3 gears with all that torque and so much multiplication.
