If you dyno your car with a 3.91;1 rear end and say your results were 280hp 325tq. If you swapped in the 4.30:1 and put it back on the dyno what numbers would come out. Would the tq be the same or higher? I believe it would be higher because tq is multiplyed be 4.3 instead of 3.91. let me know if I am right or smoking crack. The reason why im asking is because I used to have the 3.91 and now I have the 4.3 and it feels faster.
