Gears & Axles - Gear Swap

OK let see if I got these right, I have 29.5 tall drag tire on my truck with a 80-e and 4.10 gear ratio, my cam pull all the way to 6700 pretty good but Im passing the 1/4 mile in 3rd gear at 5700 rpms, will getting 4.56 get me at around 6600-6700 rpm thru the traps? Cause thats the way to use all your power band right?

Thanks in advance guys.

Use simple algebra. You have 3 varibles there 4.10 = 5700 what will 4.56 =

=6339

I was trying to look for a formula or something similar. So you guys think it will help me out?

Thanks
