Looks like I need to put stock ones in. I can get 'em from Patrick's, but how do I get the old ones out and new ones in? The crank, rods, and pistons are in, and I'd just as soon leave them be.
The cam is a nominal 2.150, but I have mic'd both the journal and the bearing, and there's about 5 thou of mismatch.
What do I need to remove and refit new bearings?
I'm also considering taking the motor to someone to re-assemble. I got too many other projects. 8-( Can anyone recommend a shop in northern California/Sf Bay area?
Thanks!

To replace the cam bearings, the crank will probably have to come out. A good machine shop should have to tools to do that work.

It should be around $30 bucks to have them replaced. If I were closer, I would do it for that.
There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!

The block was not machined. I bought it from a guy who bought it from a guy 8-) who had apparently rebuilt it. It's on its first overbore, I think - .040 over, no ridge and in general is in very good shape. I just wanted to add the 4MF (?) cam and headers for a little more top end. The truck is 4.46 rear gears and so it needs to spin a little for highway use. It's a 3/4 ton, 8-lug axle, so taller gears aren't quite so commonly available. Besides, I like the pulling power.
I'll find a local machinist willing to do it. $30 is reasonable. Heck, $50 wouldn't kill me.
Thanks!
