    I have an 87 350 Sm465 and lately when I start from a stop the whole truck bucks and kicks and it is very uncomfortable. Is this because my clutch is shot? It only has about 3000 miles on it but it is a napa clutch and I installed it myself so if is quite possible it wasnt installed correctly. What is the best clutch to run for mostly street and some dirt driving?

    Think you could have any leaks? Oil is not good for the clutch/flywheel relationship, and can ruin a fairly new clutch.

    No leaks that I can see. But you knwo what I didnt do that someone told me I should have, I didnt clean the disc with contact cleaner before I installed it.
    Would that do it?

    Well it's best to clean them, but I would've thought you would get problems sooner than you did if that was the problem. I have seen a flywheel with a nice handprint-shaped burn in them...

    It's also possible that something just went bad. Check your bolts and look for something obvious. More than likely though, no matter what is causing it, you will have to tear into it. You might as well just pull it apart and then see what's wrong, rather than trying to predict what the problem might be. It sucks to hear, cause I know its a PITA.
