Cam Bearing Installation??
I had my 390 block hot tanked at the local machine shop and they removed my cam bearings. I have my own cam bearing installer so I told them I would install them my self to save a little extra money.
My question is which way do I line the oil holes up? My factory service manual just says line them up. Do I line the oil hole in the bearing with the hole on top going to the main gallery, or do I line the hole up on the bottom to go to the crank? By looking at the oil flow diagram in the service manual it appears that oil coming from the top side (main galley) flows oil through the notches around the outside of the bearing and when it gets to the bottom it feeds the cam and crank. I could totaly be wrong on that, I am just basing that off pictures in the book. Can some one help me out so I can continue to put my engine together? Thanks,
Jeff

Camshaft bearings
Line up the holes. My service information shows oil frow going from the main galley, above the camshaft, to the cam bearings, and around the cam bearings, to the crankshaft main journals. Make sure there are holes lined up above the camshaft, and below the camshaft. Cam bearings #2, and #4 feed oil up through galleys, and into the heads, and then past one rocker arm bolt on each cylinder head to the rocker arm shaft.
Make sure the front camshaft bearing is .005 to .020 below the front surface of the block.

some things are better left to the machinist.. if your gonna do them be sure to do all the tapping the oil galley ends, mods, etc before you start this process. Cant get shavings out of there once their in. Once in test the cam for a good fit/rotation with white grease. Dont feel right, start over(or down to the machine shop) is my 2 coppers Seems my machinist only wanted 40.00 to install them...could be wrong +- ?? CRS sorry

Look up "The Poor Man's 427" and I have pics to show how to install cam bearings in a FE. Also once your done installing the bearings. Take an old cam shaft (that is clean of course) and dummy it in there to make sure it spins free. If it doesn't spin free, then you have problems. Might need a beaning knife (that's an Art in it self)to do a little shaving or you you where not careful when you installed the bearings. Don't let it go, otherwise you can spin a cam bearing!!! JMO

I have installed cam bearings before, unfortunately I did not pay attention to the orientation of them in the FE before I took it to the machine shop. Something was not right with the original bearings, as I could not remove the cam with out using a hammer to pound it out. It was a real pain in the but.
I found a video on the net of someone putting them into a 428 so I installed mine in the same way. The oil hole in the bearing was facing down towards the mains, except for the first one which has two holes in the bearing.
I test fit my new cam and it slid right in with out any hiccups. At this point I have not greased it up, or tried to turn it. I just wanted to make sure it would go in, like I said before the old cam did not come out that way. Tomorrow morning I will pull it out and grease it and see how it rotates. With a little bit of luck I will be able to continue the assembly with out any back tracking. Thanks for the info.

You just need a little bit of clean oil for the cam dummy up session. I thought you would want to take heed. If you have any problems or think you might. Take it to a machinist to make sure its right. I hate to see someone loose an engine because of that. And that wont be the first time it has happen. Glade that I can help out!!!!!
