Guest Posted August 6, 2005 Share Posted August 6, 2005 Just trying to figure this out late tonight, Car has 3.73 posi rearend, that was added , and still has the stock TH350. speedo is off 17 mph with 275/60/15 tires on it. reads 72 @ a true 55mph. So was the original rear end like a 2.73 or something along those lines ? Any good guesses as to what cable gear to run with this combo ? I have no idea whats in it now. (I'm assuming its stock from the 2.73 setup...... turns about 2700 @ 55mph. Quote Link to comment Share on other sites More sharing options...
