Cam Bearings
How hard is it to swap cam bearings? Seems to me like it would be fairly easy but I could be wrong. So people with experience let me know how it was for you.

Re: Cam Bearings
Pretty easy really, if you have The Tool...
It's basically a bushing knocker, with a cone to center the drift shaft so that it's perfectly centered and therefore drives the bearings straight.
Here's some of the parts of one.
Be aware that there are 4 different bushings in a SBC set. There are 3 ODs; the center one is the smallest, the next 2 are slightly larger OD (like .010" or something), and the front & rear are another .010" larger, but the front one has 2 holes. You want to put them all in so that the hole is at about 5:00 - 5:30 as viewed from the front, except the front one you put in so that one hole is at about 4:00 and the other at about 7:00; if you put them in wrong, especially with a hole at the top, you will end up with NO oil pressure. Works best if you put the front one in first from the rear, then the 2nd one from the rear, then the middle from the rear, then the 4th from the front, then the rear one from the front.
