Then the speedo just takes off after that ie. showing 65 - 70 at approx. 40 mph, is there a way to fix this at my level, lube and clean? truck equipped w/ 283 sbc, 350auto, 10 bolt rear, 373's?
Not sure. It was purchased this way. It does work well at 35 and under. Just spins way to fast for my actual speed, found a tutorial over on the H.A.M.B. for lubing the head. Not sure this is going to help me though as it spins too much. I would not be able to tell if it is an original or correct setup as I have no prior experience as to what this hook up should look like. Again it works like it should up to 35 mph.
