I have no problems keeping the cam and just running a 4k stall I was just concerned about long trip drivebility with this combo, and was debating if I wanted to go with 4.10s for more low end or 3.73s for a little more all around drivebility, I am currently running 22x10 wheels but may soon be running 24x10 billets. So wheel size plays into gear selection aswell.
