4.56 vs 5.13s

I'm guessing your around 3300lbs and 350hp without knowing what heads you have..... with 29.5/5.13 gear using 2 shifts you'll trap the 1/8th@5000 in 7.8 [email protected] 4.56 it'll trap@4500 which is no good...5000 ain't the best, 5500 would be 5.57's, 6000 would be a 6.18 gear according to the calc?
1/4 no's look like this
60 Foot E.T. : 1.71
1/8 Mile E.T. : 7.76
1/8 Mile Trap Speed : 87.54
1/4 Mile E.T. : 12.30
1/4 Mile Trap Speed : 109
