Rear end swap
Currently I have a 4-10 rear end in my 65 1500. Resently I install a Holley 500 and that made a world of difference. But I am still taching really high at 65mph. How much difference will I see if I swap to a 3-73. Would really like to put in a T5 but they are hard to find. I have a chance to get a Muncie 4 speed and coupled together think I might have a good combination.
