Mine runs 70mph in 6th at 1600 rpm with a 27" tire and 3.73 gear. I’m goin to 4.56 (only 3 ratios available - 3.73, 4.10, 4.56 for my 14 bolt 9.5" ring gear) to raise the cruise rpm to around 2200-2300 in 6th. In the 1/4, I’m shiftin into 4th just before and I cross the line at 3000-3200 rpm. With the 4.56s, It’ll be up around 4500-4700 rpm in fourth.
