Default Help with gear/rpm question going from 2.73 to 4.10's

So i'm tryin to figure out what RPM and in what gear i would be going through the traps in if i swap out 4.10's for my 2.73's.

Last night i went through the traps at about 6300-6400 @ 98 mph in 2nd gear with my 2.73's. I've tried figuring out the calculators and such on here but i feel like dummy and can't seem to figure it out so i figured this would make things easier...

Any help is appreciated...

Thanks!

1/8 mile track times there huh

if ur an auto at that trap speed of 63-6400 and in 2nd gear like you say that mph would be about right.
if you went to a 4.10 gear you will definately be in 3rd gear and about the same rpm level and thats both assuming ur on a 26" tall tire
