I bought a 235 engine out of a 1954 3100. This engine has been rebuilt. All the gaskets are in good shape and the oil is clean. The bolts that hold everything on like the coil and what not, back out easily. The lifters under the valve cover and the push rods look very clean, we are going to take the oil pan off this week to check the bearings. With the engine I got a coil, carb, distributor,fuel pump,water pump, a large oil filter with new lines, rebuilt starter, transmission with fairly new clutch assembly and a 55 rear end. I bought this setup from a friend of my father in law. He builds engines and drivelines for hotrods for people. This engine had come out of a 54 3100 that the guy wanted a 350 in. Oh yeah, did I mention that all this only cost me $300? I'm dying to get it in but we are taking it slow to do it right. This is by far one of my better investments for this truck.
