MTI's X1 is a reverse split at 230/227 .591/.571 112 but the R1 is closer to the two cams we have been talking about with 232/236 .575/.578 114 which I think would be a good choice in a truck since it will make power a little sooner in the rpm range than the LG or TSP cams. Plus the slightly less lift will make it better for a daily driver. The lift on my buddies WS6 almost makes it not streetable.
