The engine is from a 46, dont know all the history. Was very clean under the valve cover and outside. The plugs are a nice burn, no gunk or fouling at all. The engine runs a bit rougher than before so I put new plugs, points, leads, cap etc, need to double check the gap. Starting in second is the same, shift to 3rd, no problem, when you shift to 4th on the flat, minor thump, go up a hill and major noise. More like a thunp, rather than metalic click or detonation. The truck was sat for a few days and ran out of fuel. Put fuel in, flashed up and was a little rough at idle. Can bearings be installed in an engine with babbits?
