This distributor was installed in a 1949 Ford V8 original flathead along with a new coil, wires, plugs, Holley 4 barrel carb and electric fuel pump. The engine starts SO easy and runs strong. The distributor installed very easy, instructions great. Engine timing was not a problem.I did initially have a poor connection from ignition switch to coil, which caused it not to start. You need to make sure you have 12 volts at coil not only initially, but also when engine is cranking - the distributor needs a lot more current flow than the original points/distributor/coil setup.
