Looking at the diagram in the Steve Christ "Big Block Ford" book, it shows the oil flowing from the upper center lifter gallery, down through the cam bearings to the main bearings. The cam bearings in my block do not have oil holes to the top of the block and that center oil gallery. There is only one oil hole, and it points down to the bottom of the engine, and the main bearing saddles. I can see through oil hole in the main saddles, and see into the cam bearings. BUT... the rear most bearing is oposite the others. The single oil hole is on the top of the cam, facing the top of the engine. I can see through the oil hole in the bearing, and it looks to be matched to an oil hole in the block. I can only assume that the rear cam bearing is oiled from the lifter gallery. If so, how does the rear main bearing get oil?
I can't remember what the old cam bearings looked like. But based on the Christ diagram, the cam bearings should have two oil holes. One in the top, and one in the bottom, and the bearing should be grooved so that the oil can flow past the cam journals on to the main bearings from the upper oil gallery. My bearings only have one hole, and they aren't grooved. And neither is the journals on the cam.
I just don't understand how oil will get to the cam, and on to the main bearings with no oil feed from that center lifter oil gallery.
Do I have the correct cam bearings? I don't want to assemble the engine if these aren't the right bearings. The machine shop furnished the bearings, so I don't know if the right bearings were ordered, and installed.
It just doesn't make sense to me when I look at it.
Some of you FE experts enlighten me here....
