I have a 78 invader 340 with a rebuilt 440 in it. New pistons, crank seals NOS gaskets. the 340 ran when I switch engines. comes with two more bottom ends track is in great shape and so is the frame. It comes with two hoods one is a 440 that's original and the other needs to be painted.and the seat needs to be recovered. . $250 or trade for a different snowmobile don't care what it is only if it runs.
