New old '66 Barracuda

Do NOT flush out that engine, because doing so dislodges the "crap" buildup into the motor. On my sister in laws 64 barracuda, I removed the 318 engine and cleaned all the parts while on a engine stand. Not as much work as it sounds like becaue the engine comes out very easy. THE only mistake made was I was unable to talk my brother into reboring the engine, due to mileage on car. It made it a smoker, but the oil stayed clean for a long time after oil changes. This was done about 1984. Today I have the car here to install a rebuilt 340 and other work.
