I THINK i remember some post from before the changing of our beloved contour.org about the power output of a 3.0 running 3.0 heads with the 2.5 svt cams and computer, Im interested in this because i would like the lower compression for relability issues and such.. If anyone remembers this our could find it in search (cause i couldn't) It would be great, Also is anyone running a setup like this?
