3.73's unless you are getting some taller tires.

i agrea with the above post,you dont need 4.10`s if your spraying a 200 shot,you will run out of 4th gear and get a slower ET then if you had the 3.73`s

How size are the tires on your bird? How many inches?

If I spray A 200 shot with 4.10 and 26" tall tires, anybody have any idea what the RPM's will be at the end of the 1/4mile or 3.73's.I just havent ran it but I got a good deal on a 4.10 currie built center section,so Im deabting in changing it out.

We need to know what rpms your redline is? What HP N/A? To get an idea where you wanna be gearing wise. It's all in the whole combo not just gear ratio! 4.10's with 26" tire is 113mph@6000rpm, 123mph@6500rpm, and 132mph@7000rpm. A 28"tire is 122mph@6000rpm, 132mph@6500rpm, and 142mph@7000rpm. Now you need to know what your N/A mph is and figure how much HP your realistically putting down to the ground! Add 200HP and figure your gearing! As you upgrade HP, you can make tire height adjustments to compensate for more power! Good luck! Hopefully I was helpful!

My HP N/A to the ground is in my sig.I plan on shifting at 6600rpm since Im not making any power beyond that.

You will more than likely need 28in M/T Drags with the kind of power you are making no matter if you choose 3.73's or 4.10s...
