Wasn't sure where to post this question but since my 38 is a hot rod thought I would post my question here. Had my truck out on the road for first real test yesterday. Everything was good except I noticed that when I was doing about 45 MPH my speedometer was reading almost 60, that's a big difference. I have Stewart Warner gauges and a 350 transmission, 15 inch tires in rear. I know there are different speedometer gears, but have never had to deal with this situation before. Would appreciate some thoughts from some of you experts on how to get the speedo reading to be more accurate. Thanks for any help, Don.
