I bought a 383 4 speed car with a rebuilt engine for the engine. I took it apart today. When I went to pull the transmission it would not come out. It turned out the input shaft on the transmission was mushroomed. Apparently the crank is not machined for the input shaft and it mushroomed when it was tightened. The engine has about 10 miles on it and an hour of run time. The engine ran fine and the transmission shifted good while I had it. Is this enough to have damaged the thrust bearing or surface of the crank. I am going to pull the pan and see what I can see, but I am not too sure what to look for.
