I believe my problem are the shocks. Cause it just floats up and down a little too mmuch at high speed. I'm doing that and sway bars and an extra spring on the back and see where that gets me. front end has already been rebuilt xcept for new front shocks. Thanks for input guys. And any more is certainly welcomed. I fixed the speedo gear and i figured 160 wldve been 140. But I was doing more like 130 and not 140. But that's still getting down for me. lol
