Default Cam bearings install

I was wondering if anyone has a good write up on cam bearing installation. I just ordered about half the parts for my cam swap and I should be getting the rest in the next month or so. Since I don't have the motor out to even look, I'm just going to jump the gun and assume I will need cam bearings, but then again I'm not sure. This is a 2nd motor, completely stock, with 17,000 miles or so on it so I'm not sure how bad they could be, but since I'll already be in there, I thought why not. Thanks.

That is a job usually best left for a machine shop. Without proper tools there is agood chanche of damaging the bearings. Also there is a need to properly align oil holes while pressing the bearings in.

Well I work at a GM dealer so I am able to get the cam bearing installer from our special tools room, and any other special tools I need for it. I'm just wondering if there is a special way to do this for LT1. When I was a tech apprentace (mispelt, I know lol), I worked with one tech who did new bearings on a silverado so I have a basic idea how its done.

Being that you work at a dealer, there should be a set of factory manuals, either in paper or computerized, with all the precise procedures. Shouldn't be any different than any other SBC as the blocks are basically the same. Check section 6A3B in the service manual and look for the two chapters on Camshaft Bearings. There are two chapters first one for removal and about 10 pages after, the one for installation. Make sure the oil holes are aligned or there will be no oil going to the cam bearings.

Alright cool. I'm going to have to ask one of the guys where the manuals are because I've been at my dealer for about a year and a half and haven't seen one manual so they are hidden somewhere lol

Good luck changing the bearings if the engine is still in the car. The tool must go in the front of the engine and there is not enough room for the tool and room to hammer out the old bearings. Then they will need to be retrieved from the crankcase. The oil pan will need to be off in order to see the bearings to inspect.
You didn't say if you were going to remove the engine to do the work.
Get a micrometer and measure for proper clearance. Visually inspect the bearings for wear. At 17K miles I would say that they are pristine.

I'm definitely dropping the motor. I rather drop the motor and have space to work with and take my time instead of fighting everything inside the car.

Great idea. I took my time rebuilding my motor and was rewarded with a great running bullet.
