If you're gonna try gears I'd go with at least 4.10's otherwise you'll end the quarter part way through 4th and the extra gearing may not compensate for the time it takes for the extra shift. Your results are making me seriously think about doing a cam swap - stop it already
I was running 26.2" tall tire.
Bob,yes your right 4.10 is perfect for 1/4.

My peak comes in just shy of 6800 474rwhp, 5200 400rwtq

The cams are worth 20 RWHP.

Cam specs
.236 .425 In
.220 .425 Ex
Some cam sound at idle,drives like a stocker,throttle response furgataboutit.
