For 1/4 mile drag racing, you're gonna want to go with whatever gear allows you to cross the traps at or near redline in 4th gear.
exactly, and with 800-850 whp he should be trapping in the 140 area.
RPM Speed
6000 133
6100 135
6200 137
6250 139

6400 142

6600 146
3.73s with 28" tire
let you stay in 4th thru the traps
lets you get off the line quick and a decent foot print with the 28"

3.73's with 28" will top out in 4th in the mid/upper 120's
Proto according to my math a 4.10 on 28s would hit 6500 at 130mph. With 3.73s at 130mph would be around 5,800rpm. JD a 3.90 is close to 6100
