Well guys, I took the truck out and ran it up a little in speed. It evened out a little and wasn't vibrating as bad. By the way, it still vibrated with the clutch depressed (that was a question someone had asked). I'm thinking a combination of the tires and the driveline that I put in phase yesterday may be the issue. I noticed that the accelerator is sticking a little and I have to hit it with my foot to get the rpm's to back off. Oil pressure and temp are doing fine. Quite a bit of blue smoke on start-up and until I got it out on the road. I guess that's probably normal since the engine is rebuilt and only right now has maybe 5 miles in it. The engine runs a little rough. I had a mechanic friend time it for me when we started it up, so it probably needs a little further adjustment. I have sdome other issues such as hood alignment as it wants to keep popping open on me. Doors are rattling since I don't have the weatherstripping in yet. No door glass either for that matter. It has to be floorboarded to get close to 55, but I remember that from back before. Still alot of odds and ends to fine tune, but it'll get there. It snowed here this morning (we aren't supposed to have snow), but the roads are clear and just wet, so I'm sure the tires didn't warm up much on this short jaunt. At any rate, I feel a little better knowing I can run up the speed and it evens out a little on the vibration. Thanks for all of the posts and the recommendations gentlemen.
