Set new engine up help?
After flattening a cam years ago, I now use this very simple method.
With the timing cover off, after the cam has been installed and marks lined up, you are at #6 firing.
That is when I throw the distributor/oil pump drive in, and of course I always scribe a mark on it for later installation of the distributor.
Hopefully that makes some sense, but it takes a lot of the turning the motor over stuff out of it.
