    Default Clean sludge out of engine or rebuild?

    Okay, I cant decide whether i should clean the sludge out of my engine or just do a simple rebuild... Even if I do clean it the best I can, there still gonna be some sludge left in there... If I rebuild I know for a fact there isnt any sludge in there.... I want to be as worry free as possible and get as much power as i can... What do you guys think i should do? Rebuild? Or clean the heck out of it? 95 k1500 350 TBI

    Rebuilding it just for the purpose of cleaning out the sludge is going to be expensive for both parts & machine work, when it apparently doesn't need rebuilding, but only cleaning.
    You can clean it quite sucessfully, & sludge doesn't mean you need a rebuild (unless of course you are trying to convince your wife that you need the money for a big horsepower build lol) in which case "yes" a rebuild is the only way to get rid of that darn sludge
