more. Ive only had the truck 7months. witch is why I havent changed the
filter. To be honest I havent thought about it. I wasnt sure how much to gap the pugs. the factory thing said 42-46. so I figured 40 was good. it is the first time Ive chenged them.

Wade, I bet one of those could be your culprit. Fuel filter and plugs are the first place I would start. The fuel filters are reccomended to be changed more often on our trucks. Motorcraft FG986, I think. .040 is far too wide with a 6lb lower. Blowout usually happens at the higher RPM range and it's more noticable in a longer gear with the heavier load. The higher the boost, the tighter the gap needs to be. I think JDM told the built motor guys to gap them @ .030.
