1967 gto
Well I noticed something not good and I think this is why the cam isn’t sliding out easily. I see a tiny tiny bit of gulling of what looks like the front cam bearing ( are they aluminum) I cannot get the cam out . . I finally put a pair of big channel locks on the front of the cam and it takes some muscle to spin around but I cannot pull it out . My car ran great when I parked it last week . My goal here was just to put a 068 cam back in the motor |

Bearings are aluminum mostly.
The end of the bearing may have some build up like varnish or crud. Could try using a screwdriver/prying tool against the side of a lobe to try and push the cam while rotating it. Once passed that part may slide out easier. Try spraying with carb cleaner or even lubricate to help it slide out.

Good advice on the Cam nose though, That gets missed many times during assembly

Just as well mention that it doesn't matter whether you install the timing chain assembly with dots facing each other or dots up. I prefer installing them close together since it's just easier to visually line them up. Before dropping distributor back in rotate crank one revolution if necessary to get the cam gear with the dot up. Up until the distributor goes in the engine doesn't care whether you have cam gear dot up or down.
If the previous cam was installed without enough clearance the cam and cam bearings will self clearance with the possibility of the Babbitt melting out of the way and forming a ridge at the front of the bearings. If not too bad, pulling on that long bolt and turning the cam with a crescent wrench adjusted to catch the woodruff key might twist the cam out without dislodging the bearings. With the engine still assembled and in the car you don't have many options.
