Two 360s, One with Cam Bearing Install Issues

Cam bearing bores can be all over the map. The bores can be on the small size and the bearings can be on the big size. The cam needs to turn easily. If it does you can try different bearings or send it to have the bores machined. There is a third option. If you have an old cam cut a diagonal groove in all the bearing surfaces. About 45 degs. Coat it in oil and slid it in. Slowly turn it. it will clearance the bearings. You may want to remove it and clean out the grooves periodically. I usually want to be able to spin the cam by hand with just the sprocket on it. Make sure you clean out all the oil passages after!
