Nickey4271647545519 Posted January 14, 2011 Report Share Posted January 14, 2011 Some pretty impressive numbers right there. Quote Link to comment Share on other sites More sharing options...
NHRATA Posted January 14, 2011 Author Report Share Posted January 14, 2011 Thanks Nick.. There a nice casting to work with . I'm sure with a little more time and money I could make them flow in the 310 range and still keep the velocity up Quote Link to comment Share on other sites More sharing options...
