Everything wears in time. Has anyone ever had the cam bearings replaced during a cam swap?
How long do they last anyways?

You cant replace cam bearings while the motor is in. You will drop cam bearings into the bottom end when you tap them out. There is no need to replace them IMO cam bearings are extremeley tough bearings and are made to take cam lobes banging on it for cam swaps etc.

They are not made to take it, however they may resist damage from swaps. Bang one up and you'll find out just how tough they are not - especially stock bearings. I learned the hard way there. Mine went after 3 cam changes and I didn't think I beat them up that bad and took my time. I would believe it if it were like a durabond bearing. As it is stock cam bearings will have brass already showing in a new block - replaced the stock ones in my new block for that reason.
Not that I think that was your issue. The oil pressure will give it away if it was.

Still getting the S/C, but don't want to spend too much money on things I really don't have to have.
