Default Reared gear selection? Need advice!!

Ok my truck is getting close. Current setup is a 32" tall slick and 5.14 gears. Trucks about 3,200 lbs. Engine made 843 hp @ 6,500 rpm. Now looking at some calculators they are saying I need about a 4.23 gear ratio with a 1:1 trans ratio to come through the traps at around 6,500rpm. Does this sound right to all of you? I know the 5.14's are to low and will need to change. With my 2,600 lb car and 5.14 with the same tire and glide went through the traps at 7,800 rpm shifting at 7,500. Thanks ahead. I should mention it's a 2wd.

A 4.23 doesn't sound low enough to me. We run 1/8 though....
