If I had the choice, I would prefer to keep my 9777254 cam or buy another aftermarket with the exact same specs as my camshaft. But the mechanic who is rebuilding my engine says I need to change it. He has been working on old cars all his life and he worked on my previous car. I do not think he would have asked me to change it if was not needed.
This is the reason I am trying to replace it with an aftermarket cam that will be similar to the OEM camshaft.
