I drove my 2.6/5speed on a 750 mile trip going 75mph the whole way. Something is wrong with yours if you can't do 65. My truck could still squeeze out 65 with stock gears and 38s. I would adjust the timing. Check the vacuum advance also.

Maybe you have head winds every time you go to and from work slowing you down. <img src="/forums/images/graemlins/lol.gif" alt="" />
