so this is what my 720 sounds like when it starts up and runs. it shakes like hell. plugs, wires, cap and rotor have been done. head gasket maybe? i have minimal experience with fixing motors which is one of the reasons i got this truck, to learn on. just looking for some input from you guys who are more experienced than i.
