I took my 74 on another road trip, 468 miles each way. Last time I did this it was May with the weather warm and no roof or doors. This time it was 30 degrees the morning I left out so needless to say the heat never really kicked in. A week before I did an oil change and replaced the speedo gear and cable so now my speedometer is back up and running after being down a couple months. My 40 is pretty much stock with the f.5 trollhole carb 2.5" lift and 33" bfg mud. I'm curious as to who all else cruises around 70 mph and is that pretty good? I had to constantly ease up to not do 75. There was no wandering all over the road. minus the tranny/tcase being loud I think the only thing I would change is going to all terrain tires to cut down some noise. I'm considering doing a refreshing of the engine(gaskets and seals),the bay, and swapping the third members to 3:70.
