So i see that this has been lightly discussed but I was curious exactly how worth it is the overdrive kit. I may have to move car further north for school so its going to have to go on the interstate sometime. Not to mention being able to take i-10 so I can get to the other side of tucson in less than an hour would also be nice.
Other than the dui and the weber my engine is fully stock and I belive it has a 3.20, 7 1/4 inch rearend.
Im mostly concerned about the engine having to work too hard to keep up highway speeds. Ive tested it on a straight away(when it was still running absurdly rich) and it was able to get to highway speeds fairly easily. Not modern car fast but more like an old corolla with its ac on fast(speaking from experience lol).

Eehhh!! Back in the late 80’s, I drove a 67 mustang convertible coast to coast and back. No tac, just stock engine and auto tranny. Just pedal down. The only problem I had was I burned out the exhaust doughnut on the manifold, easy fix. Ok, speed limit was 55 but I know I did more than that!! It’s a tough engine!! As long as you have oil pressure…
Run it!!😎😎
