The engine that came out of the 66 Cat parts car is froze, stuck like really solid. I managed to get 2 of the converter bolts out but the last one is at the top. Separated the engine and trans leaving the converter attached. 3 weeks ago I filled the cylinders with mystery oil and dumped another qt down the intake. Have tried to turn it with a breaker bar and socket several times. All thats moved is the crank bolt got tighter. Any ideas of how to get the converter off without destroying it or the flex plate? Have no plans for a rebuild at this point.
