Hey guys, I have a 28 Pantera with a 598 running 800hp. It has a imco six upper with a xr lower. The lower is now trashed and in need of a new case and rebuild. So now I have options. Do I stick with a Xr lower, move to a SC lower, Max Machine SC lower. Or what? I’ve tried a 1300 six lower and that sucked. Lost 9mph which I’m not wanting to give up. What is your opinions? Thanks
