i am running the 3 speed w the hb26 and a nice tuned pipe and it gets there i know its a heavy truck but im talking on road with space to get it up there .my cen mt2 is fast!!! 45mph+_ and the sav with my set up can get almost as fast as it! just not acceleration wise it need more space to build up steam.i also run sidewinder 30% thru it.so dont tell me my truck doesnt do 40-45 as i know it pretty much does! however if your talking about a stock sav 25 w stock motor and 2 speed!! then that speed sounds about right.[8D]
