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.
